BDL bearings undergo rigorous testing to meet ISO standards. Each unit is inspected for dimensional accuracy, material strength, and performance under load. Backed by OEM/ODM service capabilities and a production capacity of 100,000 units annually.
Unlike standard bearings, BDL’s double row design offers 30% higher radial load capacity while maintaining compact dimensions. The separated inner/outer rings allow for easy mounting, reducing installation time by up to 40% in truck maintenance scenarios.
Q: What precision level should I choose for truck applications?
A: P5 is recommended for standard truck transmissions; P4 for high-performance or heavy-haul vehicles.
Q: Can these bearings handle high temperatures?
A: Yes, compatible with standard grease lubricants up to 120°C (248°F).
Q: Are replacement parts available?
A: BDL offers full after-sales support for bearing components and technical assistance.
