Bearing Blocks Archives

Type: Linear bearing (EGR series)
Load: Primarily radial loads during linear travel; limited moment load tolerance
Cage: Typically polymer or steel retainer (varies by model)
Performance: Smooth motion, low friction, good repeatability with proper alignment
Construction: Bearing housing + rolling elements/recirculating path + retainer; used on matching shaft/rail
Use cases: CNC/3D printer axes, automation slides, gantries, robotics, jigs
Note: Requires correct shaft hardness, alignment, and lubrication; avoid heavy side moments unless supported/rail type is used.

Short Description Points

Type: Linear guide (FK-FF series)
Load: Supports radial, axial, and moderate moment loads
Cage: Typically steel or polymer ball/roller retainer
Performance: High precision, low friction, smooth motion under load
Construction: Rail + carriage/block with recirculating balls/rollers
Use cases: CNC/3D printer axes, automation slides, gantries, robotics, inspection setups
Note: Requires proper rail alignment, lubrication, and installation; avoid overload beyond rated capacity

Short Description Points

Type: Linear guide (FK-FF 17 series)
Load: Supports radial, axial, and moderate moment loads
Cage: Recirculating ball elements in hardened steel; polymer retainers in some models
Performance: High rigidity, smooth low-friction motion, excellent repeatability
Construction: Hardened rail + recirculating block with ball bearings; precision ground surfaces
Use cases: CNC axes, 3D printers, automation slides, gantries, robotics, inspection setups
Note: Requires proper alignment, mounting, and lubrication; overloading reduces lifespan

Short Description Points

Type: Linear guide (FK-FF 30 series)
Load: High radial, axial, and moment load capacity
Cage: Steel ball recirculation with precision retainer
Performance: Smooth motion, high rigidity, excellent repeatability
Construction: Hardened rail + recirculating ball block assembly
Use cases: CNC axes, robotics, automation lines, gantries, precision equipment
Note: Requires precise mounting, alignment, and lubrication for maximum lifespan and performance

Type: Shaft support block (SH 12 bridged nylon)
Load: Designed for light to moderate radial loads from supported shafts
Cage: No internal cage; acts as a shaft holder rather than a rolling bearing
Performance: Provides stable shaft positioning, vibration damping, and lightweight support
Construction: Molded nylon body with bridged top design and mounting holes for frame attachment
Use cases: CNC and 3D printer frames, automation rails, robotics guides, DIY linear motion setups
Note: Best suited for lighter systems; ensure correct shaft alignment and secure mounting for smooth motion.

Type: Shaft support block (SH series)
Load: Supports radial loads from the mounted shaft and attached moving components
Cage: Not applicable (solid support block, no rolling elements)
Performance: Provides stable shaft mounting and helps maintain accurate linear motion alignment
Construction: Metal support block with precision bore for 20 mm shaft and mounting holes for frame attachment
Use cases: CNC machines, 3D printer frames, automation systems, sliding mechanisms, linear guide assemblies
Note: Proper alignment and spacing of supports improves system rigidity and reduces shaft bending during operation.

Short Description Points

Type: Pillow block bearing (SH series)
Load: Supports radial and moderate axial loads
Cage: Typically pressed steel or polymer retainer within bearing insert
Performance: Smooth rotation, stable support, low maintenance
Construction: Mounted housing with insert bearing; sealed or relubricatable
Use cases: Industrial machinery, conveyors, fans, pumps, agricultural equipment
Note: Ensure proper shaft fit, mounting alignment, and lubrication; choose correct insert for load/speed requirements
