SBF provides a full range of needle roller with many specifications. The material is made of bearing steel, with hardness of 60-64HRC and surface roughness Ra≤0.2.

The size range of cylindrical roller produced by SBF: DW: 3-30, LW: 5-50.The material is made of bearing steel GCr15 &GCr15SiMn with hardness 60-64HR.The surface roughness Ra is not more than 0.2.

SBF also produces a large number of piston pins, crank pins and other pins. Piston pins and crank pins are generally made of 20CrMo, and other pins are generally made of bearing steel. Their precision, surface hardness and roughness meet the relevant industry standards, or meet the requirements of users.
