PREMIUM METAL SHIELDED BEARINGS

Introducing the Big Ball Bearings MR74ZZ, measuring 4x7x2.5mm, each bearing is priced individually. Crafted with high quality standards, these bearings come with a robust warranty of 120 days, ensuring customer satisfaction and peace of mind.

ENGINEERED FOR DURABILITY

Constructed from High Carbon Chrome Steel (Gcr15), these bearings provide high durability, making them ideal for various applications. The advanced non-contact double metal shielding is designed to minimize friction, promoting high performance while safeguarding the internal mechanism against debris.

PRECISE TOLERANCES FOR OPTIMAL PERFORMANCE

These bearings boast an inner bore diameter tolerance of +/- 0.0002mm and an outer diameter tolerance of +/- 0.0003mm. Rated for maximum RPM speeds up to 63,000 RPM, they maintain high precision, with a maximum outer ring radial runout of 0.0004mm and inner ring radial runout of 0.0002mm.

UNDERSTANDING SEALING OPTIONS

When selecting bearings, understanding the different types of seals is crucial. We offer metal shielded bearings that excel in affordability, though they may require more maintenance than rubber sealed or PTFE sealed options. These seals help keep lubricants in while blocking contaminants out, contributing to the longevity and performance of the bearings.

GUIDE TO MATERIALS AND MAINTENANCE

Our bearings utilize either Chrome Steel or Stainless Steel, both renowned for their strength and performance. Chrome Steel is slightly more economical and effective under regular conditions, while Stainless Steel is preferred for use in harsh environments. Proper lubrication can extend the life of either type.

EXPERT RECOMMENDATIONS FOR BEARINGS

Metal Shielded Bearings are a perfect choice for on-road racing enthusiasts, offering excellent performance at a budget-friendly price. Regular maintenance is essential for use in off-road applications to ensure optimal performance. Opt for these reliable bearings for various high-temperature applications, such as Nitro vehicle clutch bells.
