Spherical Roller Bearings 22311-e1a-k-ma-t41a
Wuxi Spark Bearing Co. Ltd., based in Wuxi, Jiangsu, China, produces the spherical roller bearing model 22311‑e1a‑k‑ma‑t41a. The bearing features a 1:12 tapered bore for shaft mounting, a machined brass cage guided by the outer ring, and a T41A vibration class designed for vibrating‑screen equipment. Its internal radial clearance is designated as C4 and the design incorporates an enhanced e1 internal structure with a narrow diameter tolerance zone. The product is classified under HS code 8482.30 for international customs purposes.
The rolling elements and raceways are forged from Chrome Steel GCr15, a common bearing‑steel grade with a typical hardness of 60‑65 HRC. The brass cage provides high fatigue strength and resistance to shock, a standard feature in heavy‑duty spherical roller bearings. Typical spherical roller bearings of this series are supplied with a tolerance class of P0 and a limiting speed of up to 1 200 rpm, which aligns with the T41A vibration class requirements. While the catalogue does not list a specific dynamic load rating, bearings of comparable size usually achieve ratings in the range of 600‑800 kN.
The bearing is intended for mining, construction and other heavy‑industrial machinery such as vibrating screens, road rollers and sawtooth cutting machines. Importers often request bulk shipment in wooden crates, with each unit weighing approximately the standard for this size (typical weight around 13 kg). The listing does not disclose MOQ, lead time or Incoterms, so these details must be confirmed with Wuxi Spark Bearing before finalising a purchase. Buyers should also verify whether the supplier can provide material test certificates or conformity assessments for the bearing.

Sourcing Spherical Roller Bearings 22311-e1a-k-ma-t41a from Wuxi Spark Bearing Co. Ltd. - China Import Guide
Importers should first confirm that the bearing’s dimensions, taper ratio and vibration class match the specifications of their equipment. Request a mill test report for the GCr15 steel, a hardness certificate and any conformity documents that verify the C4 clearance and T41A classification. Because the supplier’s response activity is currently zero, verify the latest contact information before initiating negotiations.
Logistics planning must include agreeing on Incoterms such as FOB Wuxi or CIF Shanghai, confirming container loading plans and the exact weight per unit, which is typically around 13 kg. Ask the supplier to provide a detailed packing list, crate dimensions and estimated lead time, as these are not disclosed in the listing. Clarify payment terms and any required advance deposits before shipment.
Quality control should involve a third‑party inspection at the factory, focusing on dimensional checks, hardness testing of the GCr15 steel and visual inspection of the brass cage. Obtain a final inspection report and ensure that all required certificates, such as material test reports and conformity declarations, are included with the commercial invoice. Proper documentation will facilitate customs clearance and reduce the risk of receiving non‑conforming parts.
