The Split Makes the Difference. Product Catalog
The Craft Split Roller Bearing
The Craft Split Bearing is quickly becoming the global industry standard. And not just in one industry, but wherever an extremely reliable and easily replaceable bearing is a must. From mining operations to paper mills, from the marine industry to steel, for heavy industry of all types, the innovative Craft Split Roller Bearing is transforming would-be catastrophic failures into run-of-the-mill maintenance. Made in the U.S.A. at our Newport News, Virginia facility.
- Split to the shaft construction – for ease of installation and maintenance.
- Made in the USA – designed, manufactured, warehoused in Newport News, Virginia.
- Self-Aligning – the bearing cartridge and housing externally self adjust to handle up to 3 degrees of misalignment, as standard.
- Manufactured of through-hardened 52100 bearing steel (rollers, inner and outer races).
- Ductile iron standard – Cartridges, pedestal, and flange housings are machined from high strength 65-45-12 ductile iron and steel is available upon request.
- Powder coat finish for all cast parts - cartridges, housings, and flanges
- Drain plugs – on cartridges to allow purging of grease.
- Socket head hardware – SAE standard, grade 8.
- Triple labyrinth seals – Feature dovetail groove design to fully retain the O-ring material, allowing the seal to rotate with shaft to avoid shaft wear and provide superior sealing.
- Patented roller cage – The roller cage has cylindrical pockets that encapsulate the rollers and maintain an even spacing between rollers. Small sizes feature “Zamak 3” or aluminum. The cage performs as a one-piece cage when installed.
- Bronze roller cages – From 4” and up in the S1 series, and all S2 and S3 series bearings, the cages are made from 932 bearing bronze. These cages are assembled with a bolted lap joint and utilize high tensile Nylock screws.
- Economic advantage – Higher quality and longer life.
- Float (expansion) and held (non-expansion) bearing are the same price.
- Three progressively heavier duty groups – S1, S2, and S3 series to best suit load, life, and speed requirements.
- Most sizes are available from stock for immediate shipment – Normal inch sizes (1-7/16” – 12”) and metric (40 mm – 300 mm) are in stock. Larger sizes to 32”, and special designs are available upon request.
- Cylindrical bore bearings – “Straight from the shelf” standard shafting can be used, greatly reducing costs in machine design, construction, and maintenance.
- Custom work – special application bearings, housings, and cartridges are available upon request.
- Lloyd’s Register Type Approved and U.S. Dept. of Defense Approved.
- Full factory support.
- Supported by our ISO Quality Certification
