Linear Bearing Block SBR20UU (Open – 20mm Dia)

SBR20UU Linear Bearing Block, D20mm These fully supported SBR rails are made of a precision machined, hardened steel, cylindrical shaft secured to a sturdy extruded 6061 aluminum base. Designed as a cheaper alternative to profile rails they perform quite well in CNC and motion control applications where a smooth, predictable motion is desired. These rails are capable of resisting large lateral forces and are generally more tolerant to non-precision milled mounting surfaces due to their cylindrical shape making for easier installation. The bearing blocks that suit these rails are made of a durable cast aluminum housing with rows of carbon steel ball bearings secured into an ABS housing and provide there lateral force resists on a carbon steel race sleeve inside the housing.

SBRuu 20 is an open type linear ball bearing with Aluminum block mounted. The inner diameter (which is the same as the shaft diameter) is 20 mm. It can be mounted on the SBR20 Linear rails. It is very common choice for linear motion applications. The linear bearing sliding block (sometimes called pillow block) is composed of two main parts: linear bearing and self-aligning aluminum block. The self-aligning aluminum block allows for compensation of any misalignment of inaccuracy in the final assembly. The bearing cage made from special polymers allowing for smooth and noiseless operation. It is ideal and low cost solution for CNC and other machinery applications that require smooth motion with minimum friction and at the same time high rigidity and less vibration with affordable cost and easy to assemble operation.
