Many industrial operators face unexpected machinery downtime due to incorrectly selected deep groove ball bearings. The core solution is to align bearing specifications with exact application demands—load, size, speed, and lubrication. MS Bearings supplies ISO-compliant deep groove ball bearings tailored to prevent costly failures.
Determine Radial and Axial Load Requirements
Deep groove ball bearings handle primary radial loads, with limited axial loads. For example, a conveyor belt roller requires a bearing supporting 1200N radial load and 300N axial load. MS Bearings' 6205-2Z model is ideal here, as it has a dynamic load rating of 15.8kN, enough for this application. Avoid under-sizing bearings; exceeding load limits causes premature wear and pitting.
Match Bearing Bore and Outer Diameter to Shaft/Housing
Ensure bore diameter matches the shaft’s tolerance (H7 for shafts, g6 for bearing inner rings) to prevent slipping. For a 25mm shaft, select a 6205 bearing with a 25mm bore. MS Bearings lists all dimension tolerances in product datasheets, so engineers can confirm fit with housing dimensions without guesswork.
Account for Operating Speed and Temperature Ranges
Speed directly impacts bearing lifespan. Standard deep groove ball bearings (6205 series) have a grease-lubricated limit of 9500 RPM. If your application runs at 11000 RPM, opt for a precision variant with tighter tolerances. Temperature also matters: standard steel bearings work up to 120°C; high-temperature grades from MS Bearings handle up to 200°C for furnace-related equipment.
Verify Lubrication Compatibility and Quantity
Lubrication prevents metal-to-metal contact. Use lithium-based grease for most industrial uses, filling 30-50% of the bearing’s internal space. Over-lubrication causes heat buildup, while under-lubrication leads to friction. MS Bearings includes lubrication guidelines in every product package to ensure correct maintenance.

What is the maximum temperature MS Bearings deep groove ball bearings can handle?
Standard steel deep groove ball bearings operate up to 120°C; high-temperature variants extend this to 200°C, suitable for harsh environments like oven conveyors.
How often should deep groove ball bearings be re-lubricated?
For industrial machinery running 24/7, re-lubricate every 2000-3000 operating hours. For intermittent use, extend intervals to 5000 hours.
