The BGL H…TLTL series adapter sleeve mounts tapered bore bearings on plain shafts without a shoulder or special machining. Each assembly includes the sleeve, lock nut and either a lock washer or MS lock, which simplifies installation and axial adjustment. MR Industrial Accessories supplies this line to customers across the United States and Latin America.
The code breaks down into three parts. The H identifies the adapter sleeve family. The number that follows — 500, 530, 560, for example — corresponds to the bearing bore in millimeters, while the shaft itself is smaller. The TLTL suffix defines the nut and lock configuration. Typical references include H31/500TLTL, H31/530TLTL and H31/560TLTL. To select the right sleeve, match the shaft diameter and the tapered bore of the bearing you are securing.
These sleeves are found in machine tools, transmission equipment, conveyors, mills and pumps, and in steel, cement, paper and food plants where tapered bearings go onto plain shafts with h10 tolerance. The design provides secure fixing and precise adjustment, making it suitable for equipment under moderate loads and normal industrial rotation speeds.
Before mounting, confirm the shaft diameter matches the series number and that the bearing bore is tapered. The supplied lock nut and lock washer handle axial fixing; clean the surfaces and apply the recommended torque to the nut, with the MS lock preventing loosening. Bearing lubrication and shaft alignment matter for long service. Standard material is BGL nodular cast iron superior to DIN 1563 GJS 500-7 (formerly GGG50), with carbon steel or stainless steel available for different environments.
Adapter sleeves are identified by shaft diameter and construction type, so if you have a code from another brand, we can quote the closest BGL equivalent. Interchangeability depends on dimensions and tolerances, so verify compatibility with both the bearing and the shaft. Our team can help you confirm the correct option.
