RB30025 Crossed Cylindrical Roller Bearings (separable Outer Ring for Inner Ring Rotation), this type is the basic type of crossed roller bearings. The outer rings have two parts, and the inner ring is one integer. This RB crossed roller bearing are well applied to the situation which need high rotation accuracy on inner ring. For example, it is suitable for the rotary part of the indexing table of the tools machine.
Features of RB30025 Crossed Cylindrical Roller Bearings
1. High accuracy and load capacity. Precision ground V grooved ways and rollers.
2. Withstands force in any direction. Alternately crossed rollers 45º angle.
3. Easy Installation and get used to small spaces. Threaded mounting holes in standard pattern.
4. Factory preloaded for minimum axial play and low coefficient of friction.
