Specification BatteriesRequired : 1 Brand : HJZ-Drive BulletPoint1 : Flanged Metal Shielded Deep Groove Ball Bearings: Manufactured to the same principal sizes as standard bearings but fitted with metal shields, these bearings have an additional flange to allow fitting into housings flush against the shoulder of the flange. They are often used on steel tracks as guides and supports. The shields serve to offer protection to prevent ingress of debris and dust whilst retaining the grease within the bearing BulletPoint2 : Benefits: Cost effective replacement bearing, Flanged design, Metal shielded BulletPoint3 : Material: bearing steel BulletPoint4 : Inner Diameter: 25mm; Outer Diameter: 40mm; Length: 59mm BulletPoint5 : Linear bearing is more and more widely used in electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles and digital three-dimensional coordinate measuring equipment and other precision equipment or special machinery industries.
