BS2-2217-2RS/GFP9VA944 Spherical Roller Bearings, Stamping Steel Cage
The BS2-2217-2RS/GFP9VA944 Spherical roller bearings are widely used in various food processing equipment, including: presses (withstanding large radial pressure), chain elevators, submersible mixers, bakery equipment, beverage filling equipment, and food conveying systems. Specialized bearing units such as the SKF Food Line series also use chemically resistant composite material housings, making them suitable for hygienic environments requiring frequent rinsing.
The BS2-2217-2RS/GFP9VA944 bearing is a Sealed spherical roller bearings with an inner diameter of 85 mm , an outer diameter of 150 mm, a width of 44 mm. High-carbon chromium steel rings, High-carbon chromium steel rolling mlement. Its dynamic radial rated load is approximately 282889 N, its static radial rated load is approximately 316811 N. It uses CN standard radial clearance, 2RS = Contact seal, NBR, on both sides type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
BS2-2217-2RS/GFP9VA944 bearings ( 85 mm x 150 mm x 44 mm) have the advantages of Using food-grade grease and special seals, it effectively prevents contamination, improves food safety, and has a lifespan three times longer than ordinary bearings, and are therefore widely used in the Dough mixers, chocolate grinders, flour milling rollers, ice cream production lines, and various food processing and packaging equipment.

The BS2-2217-2RS/GFP9VA944 Spherical roller bearings mainly consist of inner and outer rings, drum-shaped rollers, and a cage. The outer ring raceway is spherical, providing self-aligning functionality. To meet hygiene standards, stainless steel (such as SUS440C) is often used to prevent rust, and food-grade grease is used instead of industrial grease to ensure it is non-toxic and harmless. Some models have oil grooves and oil holes machined on the outer ring to enhance lubrication performance.
Spherical roller bearings possess self-aligning properties; when the shaft is subjected to bending or there are misalignment errors during installation, they can automatically adjust to compensate for centerline misalignment and reduce abnormal loads. They have a high radial load capacity, can withstand heavy and impact loads, and are suitable for low-speed, heavy-load conditions. They are highly corrosion-resistant, meet hygiene standards, and operate with low noise and a long service life.
