Nongalling Bearing Holder

Bearings are retained on a shaft by a compressible O-ring within a receiving groove on the shaft at the mounting location.

Shaft 10 has a radial groove 11 which preferably has a greater diameter than resilient O-ring 15. Inner race 20 of bearing 21 has a larger diameter than the outer diameter of shaft 10, but the cross section of O-ring 15 is greater than the space between the bottom of groove 11 and the inner face of race 20. Thus, in assembly, inner race 20 compresses O-ring 15 into groove 11 to provide a resilient bearing surface resistant to corrosion. Use of grease can further enhance both the ease of assembly and the sealing qualities of the final assembly. Materials such as neoprene are suitable as a grease-resistant resilient O-ring. Although a single 0-ring and groove is shown, two or more sets of O-rings and shaft grooves can be used. The arrangement permits ease of both assembly and disassembly.
