| BROWNING TAPERED ROLLER BEARINGS 900/E920 SERIES FEATURES/BENEFITS HOUSING | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 900 ECCENTRIC LOCK Browning roller bearings have an eccentric locking collar that mates with the inner race for shaft hold. One end of the inner race is machined to a cam form and the mating lock collar has an off center counterbore. The wedge | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| action of the collar on the inner race secures the inner race to the shaft. This locking method tends to tighten and grip the shaft and not leave burrs as with setscrew collars. NOTE: Eccentric collars are not recommended for reversing applications. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| E920 SETSCREW LOCK This locking device has two lock collars with two setscrews to anchor the bearing to the inner race. The elastic deflection of the collar serves to help retain the bearing hold to the shaft. Double locking collars with setscrews at 120° provide improved holding power and shaft lock especially in applications with heavy vibration or unidirectional loads. Browning lock collars are black oxide coated for corrosion resistance. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 900 HOUSING - 900 Series ductile iron housings are approximately twice as strong as cast iron. This is an important feature in applications such as sawmills where heavy loads and shock conditions are normally experienced. Elongated bolt holes in the housing base permit easy replacement of competitive pillow blocks and more adjustment capability. E920 HOUSING- Browning compact solid one piece cast iron housings provide strength and load support in a wide variety of applications. Elongated bolt holes in the housing base permit easy replacement of competitive pillow blocks and more adjustment capability. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 900 SEALS - CENTRAP® labyrinth seals contain an angled flinger that rotates with the shaft, creating a centrifugal force to help keep out contamination. Excess grease purges from the seal to help remove contaminants caught in the lubricant and prevent seal damage from over lubrication. The non-contact labyrinth design reduces drag, saves energy and normally cannot be blown by overgreasing. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| E920 SEALS - Rubber contact face seals are designed to retain lubricant and help exclude contaminants. The seal is designed with a long flexible face that seals axially against the counterface. The contact seal is self purging. It retains low torque characteristics and rotates with the shaft to help reduce contaminant build-up on the seal. Its low friction reduces heat generation and wear. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
