The 606ZZ is a radial ball bearing with a single row of balls and metal shields on both sides. It allows a shaft, a non-threaded screw body or a roller to rotate smoothly in its housing or support, replacing sliding friction with rolling friction. It is suitable for guide rollers for tape or filament, small mechanisms, robotics, 3D printers and other lightweight mechanical assemblies.
The bearing has an inner diameter of 6 mm, an outer diameter of 17 mm and a thickness of 6 mm, and the code 606 indicates the miniature series with a 6 mm bore. The ZZ marking shows that both sides are protected by metal shields, which stop large dust particles from entering and keep the grease inside. The balls are kept at equal distance by a cage, between the inner and outer ring.
The main features include the two steel rings, the rolling balls, the cage, the ZZ metal shields fixed on the outer ring and the 606ZZ marking engraved on the shield. It is a passive mechanical part, without electrical power supply.
Specifications:
Type: Single row radial ball bearing
Model: 606ZZ
Inner diameter: 6 mm
Outer diameter: 17 mm
Thickness: 6 mm
Protection: ZZ metal shields on both sides
Dimensions: 6 x 17 x 6 mm
Usage:
Before mounting, check that the shaft is 6 mm and non-threaded in the bearing area, and that the housing has a diameter of 17 mm and a depth of at least 6 mm.
Clean the housing and make sure its bottom is flat, free of burrs or material debris.
Press the bearing evenly and straight. If you insert it into the housing, press only on the outer ring. If you mount it on the shaft, press only on the inner ring.
Do not apply force through the balls, as the bearing may be marked and will make noise.
Secure the shaft axially with washers, spacers or a circlip that touch only the inner ring.
Do not wash the bearing in solvents, as the grease inside is removed and ZZ shields cannot be dismantled.
After mounting, turn the shaft with your fingers. It should rotate smoothly, without grinding noise and without stiff spots.
For a good fit in a 3D printed housing, measure the hole with a caliper and adjust the size after the first test.

SUPER!!!
The 606ZZ bearing is a passive mechanical part with no power supply, pins or program, so this tutorial does not use any development board. It shows how to choose, mount and check the bearing, step by step. You use it to let a shaft, a screw or a roller turn easily, for example in guide rollers for tape or filament, in small mechanisms, in robotics and in 3D printers.
How it works:
The bearing has an inner ring and an outer ring, and between them roll the steel balls, kept at equal distance by the cage. The sliding friction between the shaft and the housing is replaced by rolling friction, which is much lower. For this reason the shaft turns easily and without large play, and the parts do not wear against each other.
The shields marked ZZ are two metal discs, one on each side. They stop large dust from entering and keep the grease inside. They are not waterproof.
The code 606ZZ is read as follows: 606 is the miniature series with an inner diameter of 6 mm, and ZZ means metal shields on both sides. Before mounting, check three dimensions. The inner diameter of 6 mm matches a shaft or a screw with a plain (unthreaded) body of 6 mm. The outer diameter of 17 mm matches a seat of 17 mm. The thickness of 6 mm is the minimum depth of the seat.
Connection:
The bearing is not connected electrically. It is mounted mechanically on a shaft and into a seat, and the table shows which part of the bearing fits with which component.
| Product pin | Connects to | Role |
|---|---|---|
| Inner ring, 6 mm | Shaft or screw with a plain body of 6 mm | Turns together with the shaft and supports it radially. |
| Outer ring, 17 mm | Seat of 17 mm in the housing or in the roller | Stays fixed in the seat and carries the load from the housing. |
| ZZ shields, both sides | Side faces of the bearing | Protect the balls and keep the grease. |
Prepare the seat with a depth of at least 6 mm, with a flat and clean bottom. If the seat is deeper, use washers or spacers that touch only the inner ring.
Mount the bearing by pressing evenly and straight. If you insert it into a seat, press only on the outer ring. If you mount it on a shaft, press only on the inner ring. The force must not pass through the balls, because it can mark them and the bearing will make noise.
Configuration:
The bearing has no buttons, adjustments or indicators. The only things you set are the fit with the shaft and the seat, and the axial fixing method. The table summarizes them.
| Parameter | Value | What to check |
|---|---|---|
| Shaft diameter | 6 mm | The bearing fits on the shaft with light pressure and has no visible play. |
| Seat diameter | 17 mm | The bearing sits in the seat without turning inside it. |
| Seat depth | Minimum 6 mm | The bearing goes in completely, without being crushed at the edges. |
| Axial fixing | Washers, spacers or circlip | The shaft does not slide sideways and does not rest on the outer ring. |
If the seat is 3D printed or milled, measure the hole with a caliper before mounting. For a printed hole, a value slightly smaller than 17 mm and a fine adjustment after the first test give a better fit than a hole that is too wide, in which the bearing turns.
After mounting, turn the shaft with your fingers. It should spin smoothly, without grinding noise and without spots where you feel resistance. If these appear, remove the bearing and check whether the seat is straight and clean.
The bearing is greased from the factory, and the ZZ shields cannot be removed. Do not wash it in solvents, because they will remove the grease inside.
Usage example:
The example is a free roller that guides a wire or a tape, mounted on a 6 mm shaft in a 3D printed support. You need the bearing, a screw with a plain 6 mm body and a suitable length, two washers and a nut.
Make in the roller a seat with a diameter of 17 mm and a depth of 6 mm on one of the faces. If you want to enclose the bearing on both faces, make seats on both sides, with a shoulder between them.
Press the bearing into the seat, keeping the pressure on the outer ring, until it reaches the bottom of the seat. It must sit firmly and must not turn in the roller.
Pass the screw through the inner ring. Place one washer on each side, so that the washers touch only the inner ring, not the outer ring or the roller.
Tighten the nut until the side play disappears, but no further. The roller must turn freely, and the outer ring must rotate without friction on the washers.
Check the result by turning the roller with your finger. If it turns smoothly and stops gradually, the assembly is correct. If it stops abruptly, the washers are touching the outer ring or the nut is too tight. Loosen the nut slightly and check again.
Common problems:
The bearing makes a grinding noise after mounting. The usual cause is pressing through the wrong ring or a seat that is out of square. Remove the bearing, clean the seat and mount it again, pressing straight and only on the ring that makes contact with the part.
The bearing turns inside the seat. The seat is too wide. Use a tighter seat of 17 mm, a retaining adhesive for bearings or a new housing with a better tolerance.
The shaft has play in the bearing. The shaft is thinner than 6 mm or is threaded in the area of the bearing. Use a shaft with a plain 6 mm body or a suitable bushing.
The bearing locks up or turns with difficulty. Usually the washers or the housing are touching the outer ring, or the nut is too tight. Leave the outer ring free and tighten the nut only until the play disappears.
The bearing makes noise after a period of work. The grease has been used up or the bearing was washed with solvent. Replace the bearing, because the ZZ shields do not allow normal relubrication.
Limitations and tips:
The bearing is designed for small and medium radial loads in light mechanisms. It is not waterproof and is not suitable for environments with fine dust, humidity or liquids, where a bearing with rubber seals is needed.
For a long service life, avoid impacts and pressing through the wrong ring, keep the seat clean and do not exceed the load for which the mechanism is designed. With the same bearing you can build guide rollers, belt tensioners, shaft supports and articulated mechanisms for 3D printed projects or robotics.
