1. Contact Angle Selection: Balancing Load and SpeedThe contact angle is the defining parameter of angular contact ball bearings, directly influencing their axial and radial load distribution capabili...

1. High Load and Misalignment ToleranceSpherical roller bearings support heavy radial and axial loads while compensating for shaft misalignment up to ±0.5° (even 1°30' under low loads) without comprom...

1. Identify the load type and directionThe core advantage of roller bearings lies in their load capacity, but different types have significant differences in their adaptability to loads:Pure radial lo...

1. Sealed Ball BearingsStructure: Sealed ball bearings feature integrated shields (e.g., metal 2Z shields) or contact seals (e.g., rubber 2RS seals) that enclose the rolling elements, preventing conta...

As a famous roller bearing manufacturer in China, we understand the critical role of selecting the right bearing type for industrial applications. While ball bearings excel in specific scenarios, roll...

1. Contact Mechanics and Load DistributionBall Bearings: Utilize spherical rolling elements that create point contact with the raceways . This minimizes friction, enabling smooth operation at high spe...

1. Severe challenges of electric forklift sealingElectric forklifts need to deal with multiple challenges such as dust intrusion, frequent start-stop shock, extreme temperature range (-30℃ to 80℃) and...

1. The core logic and design trade-offs of aspect ratioThe aspect ratio (ratio of roller length to diameter) of needle roller bearings is a key factor in balancing load-bearing capacity, rigidity and ...

1. High load capacity, adaptable to heavy load conditionsThe design feature of needle roller bearings is that they use slender needle rollers as rolling elements, which makes their contact area with t...

A. Engineering necessity of seal design (based on ASTM D4170 standard)1. Particle protection levelThe PM10 particle concentration in the forklift operating environment can reach 200-500μg/m³ (in accor...

1. Different design structuresAngular contact ball bearings: The raceways of the inner and outer rings are at a certain angle (the contact angle is usually 15°, 25°, 30° or 40°), and can bear radial a...

A. Causes of abnormal noise in cross roller bearings1. When the bearing is running continuously, it will produce a low whistle or hum. If there is a harsh hissing, squeaking and other irregular sounds...
