トラックローラーベアリング

トラックローラーベアリング is a type of bearing designed for linear or curved track systems. They are mainly used to support and guide moving parts. They can withstand high radial loads and certain axial loads under certain circumstances. This type of bearing is widely used in industrial automation, machine tools, conveying equipment, lifting machinery, robots and other fields.

Main specifications and model classification

Key parameters

Inner diameter (d): the diameter of the inner ring of the bearing, in millimeters (mm).

Outer diameter (D): the diameter of the outer ring of the bearing.

Width (B): the overall width of the bearing.

Roller type: divided into cylindrical rollers, needle rollers and ball rollers.

Rated dynamic load (C): the maximum load that the bearing can withstand in the running state.

Rated static load (C0): the maximum load capacity of the bearing in the static state.

Limiting speed: the maximum speed that the bearing can reach under specific conditions.

Sealing type: divided into open type, sealed type and dust cover type.

Installation method: common types include flange type, slider type and embedded type.
