Key Engineering Features
- Through-hardened bearing steel — raceways are hardened to deliver high hardness, wear resistance, and long service life under reciprocating load.
- Precision-ground OD and bore — ground mounting diameter and bore ensure consistent fit in standard inch-dimension housing bores.
- Steel ball recirculation circuits — 4 to 6 precision steel ball trains provide smooth, low-noise linear travel; larger bores carry additional ball rows to scale with load.
- Integral end seals on UU versions — factory pre-lubricated and sealed for reduced maintenance; relubrication fittings are available on request.
- Inch-standard interchangeability — dimensions follow industry-standard inch linear bearing sizes for straightforward replacement of comparable branded units.
- Quality assurance and customization — each unit is inspected before shipment; custom bore tolerances, special seal materials, and modified lengths supported for OEM programs.
