JenaTec SBI30-FL-C-K3 30mm Flange Block Heavy Preload Linear Guide Bearing (DMS P/N RAIL-30-BLK-80-J)

The JenaTec SBI30-FL-C-K3 is a 30 mm flange-type linear guide block from the SBI heavy-load linear rail system. It is designed to provide smooth linear motion with high rigidity and load capacity for industrial machinery and automation equipment.

The K3 preload configuration provides heavy preload for applications where increased rigidity is required and vibration, impact, or overhung loads may be present. The SBI30 FL block is the standard-length flange configuration.

This block is suitable for use with compatible 30 mm SBI-series linear guide rails. Please verify rail series, mounting dimensions, preload, and block configuration before purchase.
