Original Category VII High Speed Spherical Roller Bearings 222（K）series

Spherical roller bearings are double row self-retaining units consisting of a solid outer ring with concave raceways, a solid inner ring and cylindrical rollers with cages. The inner ring has cylindrical or tapered holes. Spherical roller bearings can withstand axial forces and high radial forces in both directions. They are designed for very high load carrying capacities.

Product Description

High speed spherical roller bearings are suitable for:

• Bearing arrangement for very high radial loads

• Must dynamically support high impact type loads

• Locating bearings with very high load carrying capacity are required

• Relatively high axial loads occur on one or both sides, in addition to high radial forces

• Dynamic or static misalignment of the shaft relative to the housing, or deflection of the shaft, which must be freely compensated by the bearing

High speed spherical roller bearings advantage

• Bearings generate less heat

• Higher accuracy and smoother operation

• Reduced friction and more energy efficient operation

• More favorable load distribution in the bearing and therefore higher dynamic load carrying capacity of the bearing

• Compact, environmentally friendly bearing arrangement, long bearing service life and high operational safety

Features of spherical roller bearings:

High speed spherical roller bearings are double row self-retaining units consisting of a solid outer ring with concave raceways, a solid inner ring and cylindrical rollers with cages. The inner ring has cylindrical or tapered holes.

Radial and axial load capacity: Spherical roller bearings can withstand axial forces and high radial forces in both directions. They are designed for very high load carrying capacities and are also suitable for the heaviest loads thanks to their as many large and particularly long roller rollers as possible. Due to the close contact between the rollers and raceways, the stress distribution in the bearing is uniform.

Rear code: The tapered bore spherical roller bearing with the rear code K and K30 is installed on the matching adapter sleeve, and it becomes the rear code K+H and K30+H type bearings. This kind of bearing can be installed on the optical shaft without shoulder, and is suitable for occasions where the bearing needs to be installed and removed frequently. In order to improve the lubricating performance of the bearing, there is an annular oil groove on the outer ring of the bearing and three evenly distributed oil holes are drilled, and the rear code is W33.
