Import Deep Groove Ball Bearing Rl4 Rm4 — Buy in Bulk from Supplier in China

The RL4 RM4 deep groove ball bearing is a radial bearing designed for moderate to high rotational speeds with minimal friction. It features a deep groove raceway that supports both radial and axial loads in either direction, making it suitable for applications where combined loads are present. The bearing’s inner and outer rings are made from chrome steel, a standard material for this category, offering high wear resistance and durability under typical industrial conditions.

This model incorporates a single-row design with a non-separable construction, typical for deep groove ball bearings, which simplifies installation and maintenance. The bearing is pre-lubricated with a standard grease compatible with most operating temperatures, reducing the need for frequent relubrication. Its cage is typically pressed steel, a standard choice for bearings in this class, ensuring consistent ball spacing and load distribution. The RL4 RM4 is engineered to meet ISO 15 standards for dimensional tolerance and running accuracy, a common benchmark for precision bearings.

These bearings are commonly used in electric motors, conveyor systems, and gearboxes, where reliability and smooth operation are critical. Industrial buyers in automotive, manufacturing, and aerospace sectors source them for machinery requiring consistent performance under varying loads. The bearing’s design allows for easy integration into compact assemblies, and its sealed variants, if specified, provide additional protection against contaminants. Buyers should confirm the exact seal type, clearance class, and lubricant specifications with the supplier to match their application requirements.

Shanghai Yulin bearing company operates from Putuo District, Shanghai, with a focus on supplying precision bearings to industrial buyers. The company is classified as an imported-tier supplier, indicating it sources or produces components meeting international standards. Its harbor trust tier reflects a baseline verification level, though the supplier’s response rate and average response time are currently unrecorded, suggesting buyers should proactively confirm availability and technical details.

The supplier specializes in deep groove ball bearings and related components, catering to sectors such as automotive, manufacturing, and machinery assembly. While the profile does not disclose production capacity, certifications, or client references, the company’s presence in a major industrial hub like Shanghai implies access to robust logistics and supply chains. Buyers are advised to request specific documentation, such as ISO compliance certificates or material test reports, to validate the bearings’ suitability for their applications.
