Rings & Pins Archives

Type: Sealing ring (Top seal type)
Load: Not load bearing; designed to maintain sealing under light contact pressure
Cage: None
Performance: Effective contamination protection and lubrication retention in rotating or static assemblies
Construction: Elastomer or composite sealing ring formed to match specified inner and outer diameters
Use cases: Bearing housings, pumps, motors, gearboxes, rotating shaft assemblies
Note: Ensure proper installation orientation and clean seating surface to maintain sealing efficiency.

Type: Bottom seal ring (AT series)
Load: Designed for sealing pressure and light contact loads rather than structural loads
Cage: Not applicable (solid sealing component)
Performance: Effective leakage control, stable sealing contact, good resistance to wear with proper lubrication
Construction: Precision molded or machined sealing ring designed to fit between mating surfaces or around shafts
Use cases: Pumps, gearboxes, hydraulic units, rotating shaft assemblies, industrial machinery sealing points
Note: Ensure correct size fit and material compatibility with fluids, pressure, and temperature conditions for best sealing performance.

Type: Seal ring (Raytools laser head sealing component)
Load: Designed for sealing pressure rather than mechanical load
Cage: None
Performance: Maintains airtight seal, helps protect optical and internal components from dust and gas leakage
Construction: Precision molded sealing ring designed to fit laser head housing grooves
Use cases: Fiber laser cutting heads, Raytools laser assemblies, industrial laser machine maintenance
Note: Ensure correct size and proper seating during installation to maintain effective sealing and prevent leakage.

Type: Needle roller bearing
Load: Designed mainly for high radial loads with limited axial load capability
Cage: Steel cage or retainer to maintain roller spacing and alignment
Performance: High load carrying capacity, smooth rotation, efficient in compact spaces
Construction: Outer ring with precision needle rollers and cage assembly
Use cases: Gear systems, transmissions, industrial machines, automotive components
Note: Requires hardened shaft or inner ring and proper lubrication for long service life

Type: Drawn cup needle roller bearing (BR series)
Load: Designed primarily for high radial loads with minimal axial load capability
Cage: Usually none (full complement needle rollers) or steel retainer depending on design
Performance: High load capacity for compact size, low friction rotation when lubricated
Construction: Thin drawn steel outer shell with needle rollers arranged in parallel
Use cases: Automotive gear systems, power tools, transmissions, compact machinery
Note: Shaft often acts as the inner raceway, so proper hardness, finish, and lubrication are critical for durability.
