SAF

Industrial Resilience

SAF pillow block bearings, derived from "Split Pillow Block with Seals," represent highly robust bearing solutions for industrial applications. Their split design allows for efficient assembly and maintenance without the need to disassemble the entire unit. Equipped with seals, they provide reliable protection against contaminants, enhancing their lifespan in challenging environments. SAF pillow block bearings are ideal for applications with high loads and stringent requirements for reliability and efficiency.

SAF Series

The housing type SAF3000/3100/3200 is specifically designed for the use of 230K, 231K, 232K series self- aligning roller bearings. The standard material for these housings is grey cast iron. The bearing seat inside the housing is precision-machined to the G7 tolerance class. The sealing is achieved through TS labyrinth seals. Upon customer request, these housings can also be adapted for cylindrical bearings and supplied in a different material.

Installation types

Flawless Integration

HBND housings demand precise installation utilizing suitable tools and employing cutting-edge mechanical mounting methodologies. Each associated component is required to adhere to specific foundational criteria.

17/16

Housing Highlights

GLH SAF and SAW housings feature a flat, square base for easy and precise mounting. Caps and bases are individually marked and not interchangeable. Suitable for grease or oil lubrication, they are made of grey cast iron and coated with a corrosion-resistant blue paint (RAL 5001), which can be repainted if needed.

Benefits

Seamless Solutions

The SAF and SAW housings excel in easy assembly, precise alignment, and individual marking of the housing base and cap. Featuring pry slots and spherical dowel pins for effortless separation, they provide clear instructions for a seamless installation. Versatile in lubrication, they offer a reliable reservoir for grease or oil with a sump in the housing base.

For SAF/SDAF bearing housings are different seal arrangements available. You can get split and unsplit labyrinthseal as well as combined-seal system like taconite seal.
