81228L1 NACHI Spherical Roller Thrust Bearing

81228L1 NACHI Spherical Roller Thrust Bearing have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers .

81228L1 NACHI Spherical Roller Thrust Bearing features
High load carrying capacity
The large number of rollers, which have an optimum conformity with the washer raceways, enables the bearings to accommodate heavy axial and simultaneously acting radial loads.
Accommodate misalignment
81228L1 NACHI Spherical Roller Thrust Bearingare self-aligning and can accommodate misalignment .
Separable design
81228L1 NACHI Spherical Roller Thrust Bearing are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition this facilitates maintenance inspections.
High speed capability
The cage designs and the optimum conformity of the rollers with the washer raceways make the bearings suitable for relatively high speeds.
Long service life
The special roller profile reduces edge stresses at the roller/raceway contact.
Low friction
The optimized roller end / flange contact keeps frictional heat at low level, even at high speeds.

81228L1 NACHI Spherical Roller Thrust Bearing are separable single direction acting axial bearings

• Able to accommodate misalignment
• Suitable for high axial and some radial loads
• Relatively high speed ratings
• Standards: DIN 728
• Series: 29200, 29300, 29400
• Application examples:
  • heavy vertical shafts
  • injection moulding machines
  • etc.

The raceway of housing washer of this bearing type is spherical with the center of the radius located on the bearing axis. The design provides self- alignment capability to the bearing. The Contact angle is approximately 45° enabling the bearing to support axial load and a small to moderate amount of radial load. NACHI Spherical Roller Thrust bearings can sustain high loads at low-to-moderate speeds.

Because of the large load capacity and self-aligning characteristics, this bearing type is often used for injection molding machines, crane hooks and other large machines. Cages are made from machined, high-strength brass or pressed steel.
