INA Drawn Cup Needle Roller Bearing 18 mm ID 24 mm OD Open End Type HK1812-B

INA HK1812-B drawn cup needle roller bearing with 18 mm inside diameter and 24 mm outside diameter is engineered for high radial load carrying capacity in a compact form factor. Its open end type and single row design make it suitable for precise rotary bearing applications in industrial machinery and mechanical equipment.

The bearing features a 12 mm race width, a parallel bore, and a sheet steel cage ensuring durability and reliable roller guidance. It has a static load rating of 10900N and a dynamic load rating of 8100N, supporting speeds up to 14000 rpm with oil lubrication and 8400 rpm with grease.

Designed with thin-walled, drawn cup outer rings, this bearing allows for reduced heat generation and lower noise during operation, leading to lower maintenance requirements and operating costs. The open ends facilitate specific lubrication setups, although the single-row version does not include lubrication holes.

Installation requires a hardened and ground shaft bearing raceway to ensure longevity and performance. This model is suitable for various industrial, manufacturing, and mechanical applications where compact, efficient needle roller bearings are essential.

Key features of the INA HK1812-B include high load ratings, durable sheet steel cage construction, and suitability for applications demanding high-speed rotation with reduced maintenance.

This bearing enables compact and easy-to-fit bearing arrangements with excellent radial load capacity. The drawn cup design and needle rollers reduce operating heat and noise levels. Open end bearing design allows suitable lubrication practices for improved performance.

Requires precise shaft raceway preparation with hardness and ground finish. Suitable for industrial, construction, and manufacturing machinery, HVAC, and fluid power equipment.
