Overview
ISO 2982-1:2013 - Rolling bearings - Accessories - Part 1: Dimensions for adapter sleeve assemblies and withdrawal sleeves - defines standardized dimensions and boundary limits for adapter sleeves and withdrawal sleeves used with rolling bearings. The standard covers sleeve tapers of 1:12 (adapter and withdrawal sleeves) and 1:30 (withdrawal sleeves), giving designers and manufacturers the dimensional data needed for consistent shaft mounting, dismounting and assembly of bearings.
Key Topics
- Boundary dimensions for adapter sleeve assemblies and withdrawal sleeves (provided in Tables 1–5).
- Taper specifications: 1:12 for adapter sleeves and for some withdrawal sleeves, and 1:30 for other withdrawal sleeves.
- Dimensional parameters included:
- sleeve bore and outside diameters,
- adapter/withdrawal sleeve lengths (overall and component lengths),
- outside diameter of suitable locknuts,
- distances from the bearing small-bore face to the outer face of the locknut and to the outer face of the bolt head,
- overall length of the withdrawal sleeve plus bearing ring.
- Range coverage: dimension series correspond to the bearing dimension series specified in ISO 15; tables cover a wide range of bore diameters (small to very large shaft sizes).
- Notes on threads and locking devices: thread lengths are not specified by ISO 2982-1 but are required to be appropriate for securing or withdrawing bearings. Locknut, lockwasher and locking clip dimensions are referenced to ISO 2982-2.
- Terminology and symbols follow ISO 5593 and ISO 15241.
Applications
- Ensures interchangeability of adapter sleeves, withdrawal sleeves and locknuts across manufacturers.
- Guides mechanical designers and machine builders when specifying shaft-mounted rolling bearings and accessory components.
- Used in manufacturing and quality control to verify dimensional conformity of sleeves and locknuts.
- Facilitates safe and effective mounting and dismounting of bearings using standardized adapter and withdrawal sleeves, improving maintenance efficiency in gearboxes, motors, pumps, and other rotating machinery.
Who uses this standard
- Bearing and accessory manufacturers (production, CNC shops)
- Mechanical designers and OEMs specifying shaft assemblies
- Maintenance and reliability engineers responsible for bearing replacement
- Procurement and standards teams ensuring component compatibility
- Test labs and quality inspectors verifying dimensional compliance
