Sid Harvey B70-1R Bearing Assembly

Sid Harvey's B70-1R Bearing Assembly is a remanufactured Bell & Gossett circulator bearing replacement (Sid Harvey Item: B70R; OEM 189100) designed for 1", 1-1/4", and 1-1/2" cast iron or bronze Bell & Gossett pumps. This remanufactured unit comes from Sid Harvey's Pumps & Bearing Accessories program and carries the Bell & Gossett brand, providing a like-new bearing replacement for aging residential circulators without replacing the entire pump. In Sid Harvey's catalogs, the B70R family is listed among circulator bearing assemblies with options for standard or high-temperature seals on B70R configurations. Catalog cross-references show B70-1R as part of the same family, including compatibility with older Bell & Gossett HV/ booster models; a lead-free variant 189163LF is also listed as a cross-reference, replacing Bell & Gossett 189163 and related numbers (189101, 189102, 189103). This makes the B70-1R a practical, OEM-backed remanufactured option for maintaining or reviving residential circulator systems without the expense of a new pump.
