NACHI 6016-ZNRC3 Single Shield Deep Groove Ball Bearing 80x125x22 mm, C3, snap ring
Available
The NACHI 6016-ZNRC3 is a single row deep groove ball bearing with one metal shield (Z) and a snap ring groove with snap ring fitted. It measures 80 x 125 x 22 mm (bore x outer diameter x width) and carries a basic dynamic load rating of 47,500 N and a basic static load rating of 39,500 N.
Deep groove bearings are the most widely used ball bearing type: they carry radial, axial and combined loads and run at high speed with high running accuracy. This one has a radial internal clearance of C3 (25 to 51 µm radial).
Where this product is used
- Electric motors and generators
- Pumps, fans and blowers
- Gearboxes and industrial transmissions
- Conveyor rollers, idlers and pulleys
- Power tools, appliances and general industrial machinery
Features
- One metal shield (ZE) forms a labyrinth clearance on one side; the other side is open for relubrication or grease inspection
- Low friction torque and excellent high speed capability, with good grease retention and dust protection
- Snap ring groove with snap ring fitted in the outer ring (NR), which simplifies housing design and mounting
- C3 radial internal clearance (25 to 51 µm for a 80 mm bore), larger than Normal
- Basic dynamic load rating 47.5 kN, static 39.5 kN, with NACHI boundary dimensions to the ISO/JIS standard plan

Selecting the right option
Shielded bearings (ZE one side, ZZE both sides) arrive grease-filled with a labyrinth clearance, so they keep friction low and speed capability high while adding dust protection. Shields are not suited to water. For standard filled grease the recommended temperature range is -25 to 120 °C.
Fitting and use
Check the load and speed against the catalogue figures in the table before ordering, and apply a suitable safety factor. These bearings must always carry a minimum radial load so the balls roll rather than slide, and heavy axial loads should be checked with AIMS before ordering.
Press the ring that is being fitted, not the other ring or the balls: force goes through the side face of the inner ring on a shaft and the outer ring in a housing.
Shielded bearings are built for inner ring rotation, so they are not suited to high speed outer ring rotation. Do not wash or heat shielded bearings before mounting.
