The Bosch Rexroth COMPACT LIN. BUSH. KBC-20-D (R065812040) is a high-performance compact linear bushing designed to offer a reliable linear motion solution with small outer dimensions and highly compact construction. This model features a shaft diameter of 20 mm and comes with one seal, providing protection against contamination while maintaining a standard radial clearance. The COMPACT LIN. BUSH. KBC-20-D is engineered for general requirements where cost-effectiveness is key without sacrificing quality or performance. It boasts a high dynamic load rating and long service life, which are made possible by its hardened segmental load-bearing plates that ensure ball conformity within the running track. This enables the bushing to handle high travel speeds efficiently. An integrated metal retainer, approximately 0.5 mm larger than the outer diameter of the shaft diameters ranging from 3 to 50 mm, ensures a secure fit in the housing bore without any additional retention needed. The bushing also features multiple lubricant reservoirs for extended lubrication intervals or potentially offering lubrication for life, depending on operating conditions. Furthermore, this model is designed to prevent jamming through its pockets that collect any dirt ingress, ensuring smooth operation over time. The bushing's maximum dynamic load capacity (Cmax) and maximum acceleration (amax) are optimized for robust performance, while its friction coefficient remains low under heavy loads. With an ambient temperature range of -30°C to +80°C and a breakaway force specified by Bosch Rexroth standards, this linear bushing is suitable for various applications where precise linear movement is required. The overall design simplifies mounting processes as it can be pressed onto the shaft without extra securing measures. The COMPACT LIN. BUSH. KBC-20-D has an outer diameter of D=32 mm and length L=45 mm with a weight of 0.1 kg, making it an ideal choice for space-constrained installations where efficient linear motion is essential.
