Sealmaster Bearing RPB 207-CR2 Solution

A short bearing life was experienced on competitor’s bearings. During inspection of failed bearings their was evidence of water ingress, contamination, misalignment and vibration. The bearings are exposed to gritty water run-off and constant wear from vibration and misalignment caused by the counterweight compensating for changes in belt loading. Misalignment distorted the housing-mounted seals on the existing bearings, allowing water into the bearing chamber, causing the failure.

Sealmaster® Solution

The Sealmaster® RPB-CR tapered roller bearing was selected which is self-aligning bearing with race-mounted contact seals. The bearing can tolerate +/-3 degrees of static shaft misalignment. Because the seals are integral to the bearing cartridge insert, they remain in positive contact with the inner ring when the bearing operates within the allowable range of misalignment. Excellent sealing results in superior performance when exposed to wet, dirty conditions.

Cost savings on maintenance and replacement parts; increased production uptime.
