Import Bearing Outboard 20616-1 For Mission — Buy in wholesale FOB from Supplier in China

The 20616-1 outboard bearing is a replacement spare for the bearing housing assembly at the non-drive end of Mission MAGNUM I centrifugal pumps, stock number 648408201S. It serves pump frame sizes 8x6x14, 6x5x14, 6x5x11, 5x4x14, 5x4x11, 4x3x13, and 3x2x11, covering a broad flow and head range in drilling and well-servicing operations. The bearing is positioned outboard of the impeller, meaning it carries primarily radial loads from the overhung impeller and any residual axial thrust from volute pressure imbalance. Exact material specification, whether through-hardened carbon steel or carburised alloy, is not stated and must be confirmed with the supplier.

Mission MAGNUM I pumps are engineered for abrasive fluid service in oilfield drilling, production, and industrial slurry duty. The open impeller with wide-tipped vanes and tangential suction eye reduces inlet recirculation and improves wear life when handling sand-laden mud or completion fluids. Fluid ends are available in Magnachrome, hard iron, stainless steel, and aluminium bronze, though the bearing itself is a dry-running or grease-lubricated rolling element separate from the wetted end. Standard industry practice for such outboard bearings is a sealed spherical-roller or cylindrical-roller design with heavy-section outer rings to resist housing distortion in pump skid frames. Lubrication is typically lithium-complex NLGI 2 grease with extreme-pressure additives for shock loading during startups.

Buyers of this bearing are drilling contractors, pump rebuild shops, and oilfield equipment rental companies servicing onshore and offshore rigs. The part is critical to MAGNUM I maintainability because the pump's split-case design permits bearing replacement without removing the volute or piping. Import buyers should confirm whether Hebei Tobee supplies the bearing as an OEM-licensed part or an aftermarket equivalent, as this affects warranty coverage and interchangeability. No price, MOQ, or lead time is listed, so direct negotiation is required. Payment and Incoterms are not stated.

Hebei Tobee Pump Co., Limited is located in Shijiazhuang, Hebei Province, postal code 050000, a region with a concentration of slurry pump and wear-part manufacturers. The supplier holds a harbor trust tier, indicating a registered business presence, but the response rate is recorded at 0.00 percent with no average response time, suggesting limited active engagement through platform messaging. Buyers should initiate contact via direct email or telephone and expect to verify the company's actual production or trading capacity independently. The address format in the source data contains repeated line breaks, which may reflect an automated extraction rather than a verified corporate registration.

The company positions itself as a supplier of pump spare parts for Mission and other oilfield pump brands. No factory area, employee count, year of establishment, or annual turnover is provided in the listing. The product range implied by the description covers not only bearings but also impellers, volutes, and shaft assemblies in various metallurgies. There is no claim of OEM authorisation from Mission or its parent company, so buyers should treat the part as an aftermarket replacement unless a licence agreement is documented. Certification details such as API Q1 or ISO 9001 are not mentioned.
