Type: Thrust needle roller bearing set (AXK series with 2 AS washers)
Load: Designed for high axial loads, minimal radial load capacity
Cage: Steel cage retaining precision needle rollers
Performance: Low friction axial rotation with high load capacity and compact height
Construction: Needle roller cage assembly (AXK) combined with two thrust washers (AS)
Use cases: Gearboxes, automotive assemblies, machine tools, steering systems, industrial machinery
Note: Ensure correct lubrication and proper washer alignment; not intended for significant radial loads.

Type: Thrust needle roller bearing set (AXK + 2AS series)
Load: Designed for high axial loads, not intended for radial loads
Cage: Steel cage holding needle rollers in a thrust cage assembly
Performance: Low friction rotation with high axial load capacity in compact spaces
Construction: Needle roller cage assembly combined with two hardened AS thrust washers
Use cases: Gearboxes, automotive assemblies, machine tools, pumps, and industrial machinery
Note: Requires hardened and flat running surfaces and proper lubrication for best performance and durability.

Type: Axial needle roller and cage thrust assembly with thrust washers (AXK plus AS)
Load: Heavy axial loads in one direction; minimal radial load capacity
Cage: Steel cage holding needle rollers
Performance: High axial stiffness and load capacity in tight space
Construction: Roller and cage thrust unit plus two thin thrust washers
Use cases: Gearbox thrust support, pump/compressor axial support, machine tool thrust points, industrial drives
Note: Requires matching raceways on shaft/housing with correct washers, and proper lubrication for long life.

Type: Thrust needle roller bearing set (AXK cage assembly with two AS washers)
Load: Designed to support high axial loads, not suitable for radial loads
Cage: Steel cage guiding needle rollers for even load distribution
Performance: Low friction axial movement with high load carrying capacity
Construction: Needle roller cage assembly paired with two hardened thrust washers
Use cases: Gearboxes, transmissions, machine tools, pumps, and industrial equipment
Note: Requires proper lubrication and correct axial alignment for optimal service life

Type: Thrust needle roller bearing set (AXK bearing with 2 AS washers)
Load: Designed primarily for high axial loads; not suitable for radial loads
Cage: Steel cage guiding needle rollers for uniform load distribution
Performance: Low friction axial rotation with high load capacity in a compact space
Construction: Needle roller and cage assembly (AXK) combined with two hardened AS thrust washers
Use cases: Gearboxes, automotive systems, machine tools, pumps, industrial rotating assemblies
Note: Requires hardened, flat running surfaces; ensure proper lubrication and avoid radial loading.

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.

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: Reciprocating piston pump (positive displacement)
Load: Handles high-pressure loads with steady flow output
Cage: Not typically cage-based; uses piston, seals, and valve assemblies
Performance: High efficiency, accurate flow control, capable of very high pressures
Construction: Cylinder block, reciprocating piston, inlet/outlet valves, seals, and drive mechanism
Use cases: Hydraulic power units, chemical injection, pressure cleaning, oil transfer, industrial fluid systems
Note: Requires regular seal maintenance and clean fluid supply; not ideal for highly abrasive or contaminated fluids without proper filtration

Type: Submersible pump (water/sewage/deep well types)
Load: Handles hydraulic load based on fluid head and flow demand
Cage: Not applicable (sealed motor and impeller assembly)
Performance: High efficiency, consistent flow, self-priming due to submerged operation
Construction: Sealed motor housing, impeller, shaft, mechanical seals, and waterproof cable
Use cases: Borewells, drainage pits, sewage systems, irrigation, construction sites
Note: Must remain submerged during operation for cooling; running dry can damage the pump
