SKF Pillow block housing SONL 228-528

SONL plummer (pillow) block housings are specially designed for oil lubrication. They can accommodate high temperatures and bearings operating at high speeds. They have a strong, stiff design and are characterized by a number of built-in features that maximize the effects of the lubricant and extend bearing service life.
SONL plummer block housings are split housings and have four holes cast into the base for attachment bolts.

SONL housings can be used with selfaligning ball bearings in the 22 series, spherical roller bearings in the 222 series, and CARB bearings in the C 22 series with either a cylindrical or tapered bore, ranging from 75 mm up to 240 mm, to cover the most common shaft sizes.

Standard SONL plummer block housings are made of grey cast iron. For applications that require extra strength and resistance to shock loads, housings made of spheroidal graphite cast iron are available.
