The BGL HA series adapter sleeve mounts bearings with a tapered bore onto plain shafts, eliminating the need for a shoulder or special machining. Each unit comes complete with the sleeve, lock nut, and either a lock washer or MS lock, depending on the model. The standard material is BGL nodular cast iron, which exceeds DIN 1563 GJS 500-7 quality, with carbon steel or stainless steel available for specific applications.
The HA series code consists of the fixed prefix followed by a number that denotes the size. Examples include HA204, HA206, HA207, HA208, HA209, HA210, HA211, and HA212. This number does not represent a direct diameter; it identifies the combination of sleeve, lock nut, and lock that matches a particular tapered roller bearing size. Always provide the complete part number when requesting a quote so we can confirm the exact component.
These sleeves are used where a bearing is mounted on a plain shaft and requires secure, adjustable fixing. They are common in conveyors, mills, mixers, pumps, fans, and agricultural machinery. In food processing, cement, and mining plants, their ability to be mounted and dismounted without a hydraulic press is a practical advantage.
When selecting a sleeve, consider the shaft diameter, the tolerance (maximum h10), and the tapered roller bearing type. The lock nut adjusts the bearing's internal clearance, while the lock washer or MS lock prevents loosening. Lubricating the thread and tapered seat before assembly eases mounting and protects against wear. Proper shaft and housing alignment also affects performance.
BGL HA sleeves are interchangeable with other brands using the same nomenclature, such as SKF, FAG, or NTN, provided the part number and dimensions match. This simplifies replacement in existing equipment. If you are unsure, send us the bearing part number or shaft size and we will identify the equivalent you need.
