SS2204-2RS / S2204RS / 2204- TVH Stainless Steel Self - aligning Ball Bearing with Rubber Seal , 20*47*18mm

SS2204-2RS, S2204RS and 2204-TVH share identical core dimension 20×47×18mm double row self-aligning ball bearing, differentiated by material, seal and cage design:

• SS2204-2RS / S2204RS: Stainless steel material, double-sided 2RS contact rubber seals, anti-rust for humid, corrosive workshop environments
• 2204-TVH: Standard GCr15 bearing steel, open type without seal, TVH nylon polymer cage for high-speed clean dry equipment

Spherical outer ring raceway design allows automatic compensation of shaft deflection, installation misalignment and housing deformation, simultaneously bear radial load and bidirectional light axial load. Widely used for textile rollers, printing machinery, food processing equipment, fans, conveyors and general industrial transmission assemblies, two material/seal versions meet dry industrial and wet corrosive production line demands separately.

1. Spherical outer ring self-aligning structure automatically offsets shaft bending, assembly misalignment and equipment frame deformation, avoid bearing clamping and abnormal noise caused by poor coaxiality
2. Two complete variant lines for one size: stainless sealed SS2204-2RS for corrosive wet workshops; nylon cage open 2204-TVH for high-speed dry production lines, one-stop purchasing for different workshop conditions
3. SS2204-2RS stainless steel body excellent anti-rust performance, double 2RS rubber seals block water vapor, food residue, chemical dust and liquid splash, extend service life of humid equipment
4. 2204-TVH PA66 nylon lightweight cage reduces rotation friction, stable high-speed operation, good heat dissipation for continuous long-shift textile and printing equipment
5. Double row ball structure provides balanced radial load capacity, withstand slight bidirectional axial load, stable operation under alternating light-medium load
6. Superfinished raceway and steel ball surface minimize friction torque, low vibration, silent running for precision roller transmission
7. Support customized clearance grades (CN/C3), high-temperature/food-grade grease, OEM laser marking and neutral vacuum anti-rust packaging for global industrial spare parts distributors
