Browning Split Taper® bushings are an excellent choice for commercial belt drive HVAC applications. They are easier to install and offer greater bore capacity than other bushing systems. In addition, they are supplied with large heat-treated capscrews so maximum pressure can be applied without any special tools.

Single and Double Groove Sheaves

Mounted Ball Bearings for Commercial Duty Applications

Rubber Mount Cartridges and Pillow Blocks
Rubber Mount Cartridges and Pillow Blocks

Low-cost rubber cartridges are most common in light commercial HVAC applications. The cartridge is designed to fit into HVAC web-mount supports. The rubber cartridges adjust with misalignment and dampen noise and vibration. Available with setscrew, BOA concentric and eccentric locking.

Lubricated for Life
Lubricated for Life

Browning rubber mounted ball bearings are permanently sealed and cannot be relubricated.

AH Housing Fit
AH Housing Fit

Air Handling (AH) ball bearings are manufactured with a distinct AH housing fit. This allows the bearing to properly self-align when mounted on lightweight frames. Improper self-alignment creates high-stress zones between the ball and ball-path that can significantly reduce bearing life.
