Frequently Asked
Questions

Bearing selection depends on several key parameters: load type (radial, axial, or combined), rotational speed, operating temperature, space constraints, and required service life. Our engineering team follows ISO 281 life calculation standards.

To get a precise recommendation, please provide: shaft diameter (d), housing bore (D), applied load (kN), speed (rpm), operating environment, and any lubrication constraints. Send your specifications to info@skfus.com and we will respond within 24 hours with a full selection report.

We are authorized distributors for 15+ global bearing brands, including SKF, FAG, NSK, NTN, TIMKEN, INA, IKO, Koyo, and Nachi.

Our product range covers:

• ▸Deep groove ball bearings, angular contact ball bearings
• ▸Tapered roller bearings, cylindrical roller bearings, spherical roller bearings
• ▸Needle roller bearings, thrust bearings, spherical plain bearings
• ▸Linear guides, ball screws, bearing housings, seals and lubricants

Yes. Our technical team has 10+ years of industry experience in bearing failure diagnostics. Common failure modes we analyze include: fatigue spalling, brinelling, corrosion, lubrication failure, misalignment, and contamination damage.

To initiate a failure analysis, please send clear photos of the damaged bearing (inner ring, outer ring, rolling elements, cage), operating conditions, and maintenance history to info@skfus.com. We will provide a written root cause report and corrective bearing recommendation.

For temperatures above 120°C, we recommend high-temperature greases with polyurea or PTFE thickeners, such as SKF LGHP 2 (rated to 220°C) or equivalent. Above 200°C, solid lubricant coatings or oil mist lubrication systems should be considered.

We can supply matched bearing + lubricant packages from SKF, FAG, and NSK specifically designed for furnace, kiln, and hot-process applications. Share your operating temperature range and speed factor (n·dm) for a tailored recommendation.

Yes. We provide full technical documentation including dimensional datasheets, load rating tables, tolerance class specifications, and 2D/3D CAD models (STEP, DXF) for all stocked products.

For EPC and engineering institute clients, we can also prepare customized project documentation packages including material certificates, inspection reports, and compliance declarations. Contact us with your model number list to request documentation.

Our bearings are deployed across a wide range of demanding industries, including:

Yes. We specialize in full-project supply management for EPC contractors and engineering institutes. Our service covers BOM review, multi-brand sourcing, phased delivery scheduling, documentation packages, and customs clearance support.

We have experience supporting large-scale projects in the energy, chemical, and marine sectors across Belt & Road countries. Share your project BOM and timeline and we will provide a dedicated project quotation within 48 hours.

We support both small trial orders and large bulk orders with no fixed MOQ. Our advanced WMS warehouse management system allows us to fulfill orders from a single piece to tens of thousands of units.

For standard stocked models, we can typically ship within 3-7 business days. For large project orders or non-stocked items, lead time is confirmed at quotation stage. Contact us to discuss your volume requirements and get the best pricing tier.

Yes. We serve 60+ countries and provide door-to-door delivery with full logistics support. Our team is experienced in handling complex customs clearance procedures, including export documentation, HS code classification, and country-specific import compliance.

We have particularly strong logistics networks in Belt & Road regions including Russia, UAE, Saudi Arabia, Turkey, and Singapore. Shipping options include air freight, sea freight, and express courier depending on urgency and volume.

We accept T/T (bank transfer), L/C (Letter of Credit), and Western Union for international transactions. Payment terms are negotiable based on order size and relationship history.

For new clients, we typically require 30-50% deposit with balance before shipment. For established long-term partners, we offer flexible NET payment terms. All transactions are backed by formal commercial invoices and packing lists.

All products are sourced directly from authorized brand channels. We operate a three-level quality inspection system: incoming inspection, in-process inspection, and outgoing inspection -- aligned with ISO 9001 standards.

Each shipment is accompanied by original manufacturer packaging, traceable batch numbers, and inspection certificates. We provide material test reports and third-party inspection services upon request. Counterfeit products are completely eliminated from our supply chain.

Yes. We support non-standard bearing customization including modified internal geometry, special tolerance classes (P4, P5, P6), special materials (stainless steel, ceramic, polymer cages), special coatings, and custom sealing arrangements.

To initiate a custom order, please provide your technical drawing or dimensional requirements, load and speed parameters, operating environment, and target quantity. Minimum quantities for custom production depend on the complexity of the specification -- contact us to discuss feasibility.

Yes. We offer customized packaging solutions including vacuum-sealed anti-corrosion packaging for long sea voyages, anti-static packaging for semiconductor applications, and cleanroom-compatible packaging for pharmaceutical and medical device manufacturers.

Custom labeling, RFID tagging, and serialized tracking are also available for large project orders. All packaging is designed to meet the destination country's import inspection requirements.

We can facilitate OEM and private label arrangements through our manufacturing partners for clients with sufficient volume requirements. This typically applies to standard bearing types where the client requires custom branding, modified specifications, or exclusive supply agreements.

Please note that for branded products (SKF, FAG, NSK, etc.), we supply only genuine authorized products and cannot apply third-party branding to these items. OEM arrangements apply to our manufacturing network products only.

Lead times for custom orders vary based on complexity:

Exact lead times are confirmed at the quotation stage. We recommend contacting us as early as possible in your project planning cycle.

Absolutely. We regularly assist industrial equipment factories and plant maintenance teams with bearing upgrades -- replacing obsolete or discontinued models with modern equivalents that offer improved load capacity, speed ratings, or contamination resistance.

Our engineers can perform cross-reference matching across all major bearing brands, identify dimensional equivalents, and recommend performance upgrades where applicable. Provide us with the old bearing model number or dimensions and we will suggest the best available replacement.
