Product information "BRO - MAS® Cylindrical bushing BSZ"
Customised design, corrosion-resistant, grooves for better lubricant distribution. High loads, impact loads, wear-resistant, corrosion-resistant.
BRO-MAS is a plain bearing requiring maintenance, is suitable for operation in contaminated environments, has good corrosion resistance, and is insensitive to shock loads. Oil or grease lubrication is needed. Additional lubrication grooves or holes significantly reduce relubrication intervals and improve lubricant distribution. (IS=Internal lubrication; AS=External lubrication; AIS=External and internal lubrication; OS=Without lubrication)
