FUNCTION - Linear Motion Ball Bearing is a linear motion system used in conjunction with a cylindrical shaft for infinite travel. SMALL LOAD - Since the bearing ball is in point contact with the shaft, the load used is small. HIGH PRECISION - The steel ball rotates with very low frictional resistance, resulting in high precision smooth motion. PREMIUM STAINLESS STEEL - Made of high quality stainless steel, chrome-plated treated, wear-resistant and durable. WIDE APPLICATION - Widely used in CNC equipment, electronic machinery, equipment sports machinery, medical machinery, packaging machinery, food machinery, printing machinery, automation equipment, etc. Product Description Specification: Item Type: Square Flange Linear Motion Ball Bearing Bushing Model: LMK10LUU Inner Diameter: 10mm Material: stainless steel (chrome plated) Hard tape depth: 0.8-0.3mm Straightness: 1000mm 3.5um Rounding: 0.003mm Package List: 1 x Bearing
