1 Pcs HK 18x24x20 Needle Roller Bearing
Key features
- HK series bearings use an open end drawn cup structure, suitable for through shaft positions and compact radial bearing arrangements.
- The thin drawn cup outer ring helps reduce radial installation space, making it suitable for gearboxes, motors, drive mechanisms and compact industrial equipment.
- The cage structure helps keep the needle rollers evenly spaced for smooth rotation. Please confirm shaft size, housing bore, load, speed and lubrication method before use.
- Suitable for reducers, gearboxes, motors, automation equipment, transmission units, hand tools, textile machinery, printing machinery and general industrial replacement.
- Keep the shaft, housing and bearing clean before installation, press evenly with proper tools, apply suitable lubrication and avoid direct impact on the needle roller or cage area.
The HK series needle roller bearing is an open end drawn cup needle roller bearing designed for compact mechanical assemblies that require radial support. This type commonly uses a thin shell outer ring with a needle roller and cage assembly, making it suitable for gearboxes, motors, reducers, drive equipment, automation systems, hand tools, textile machinery, printing machinery and general industrial replacement applications. The open end structure is suitable for through shaft arrangements or bearing positions where both ends need to remain open. The thin drawn cup outer ring helps reduce the radial section, making it useful for space-limited equipment designs. Since HK series bearings are commonly supplied without an inner ring, the shaft surface usually works as the raceway. Please confirm shaft hardness, surface finish, dimensional accuracy, housing bore, working load, speed range and lubrication requirements before purchase. During installation, keep the bearing and matching parts clean, use a proper pressing tool for even installation, and avoid direct impact on the needle rollers, cage or outer ring edge. Proper installation and suitable lubrication help support stable bear
