Bearing/Slider: Travel Speed Up to 5 m/s

Component Specifications

Definition

A mechanical component designed to facilitate low-friction linear motion along a fixed axis, typically consisting of rolling elements (balls or rollers) housed within a carriage that moves along a hardened steel rail. In lift columns and scissor arms, it ensures precise vertical positioning, load distribution, and minimal wear during extension/retraction cycles.

Working Principle

Operates on rolling contact mechanics where balls or rollers reduce sliding friction between moving surfaces. The carriage moves along a precision-ground rail, converting rotational forces from actuators into smooth linear motion while supporting axial loads and moments.

Materials

Carriage: Carbon steel or aluminum alloy; Rolling elements: Chrome steel (AISI 52100) or ceramic; Rail: Case-hardened steel (HRC 58-62); Seals: Nitrile rubber or polyurethane.

Frequently Asked Questions

What is the difference between a bearing and a slider in this context?

Bearings typically refer to rolling-element types (ball/roller) for high precision, while sliders may use plain or composite surfaces for simpler applications; both serve linear motion functions in lift mechanisms.

How often should lubrication be maintained?

Lubrication intervals depend on usage: typically every 500-1000 operating hours or 6 months, with high-cycle applications requiring more frequent maintenance.
