# deep groove ball bearing 6200 series

Bearing lubrication issues cause 36% of industrial machinery downtime, according to MS Bearings data. This guide identifies top lubrication-related failures and provides step-by-step fixes to reduce unplanned stops. We focus on practical solutions for 6200-series deep groove ball bearings, the most widely used in conveyor systems and pumps.

## Incorrect Lubricant Type Selection

Using the wrong lubricant viscosity leads to 28% of bearing overheating incidents. For example, a conveyor bearing operating at 120°C needs a synthetic grease with ISO VG 220, not a mineral-based grease rated for 80°C max. Always check the bearing’s SKF or FAG specification sheet for viscosity requirements. MS Bearings offers a cross-reference tool to match correct lubricants to specific bearing models.

## Over-Lubrication and Under-Lubrication

Over-lubrication causes friction buildup, while under-lubrication leads to metal-to-metal contact. For a 6205 bearing, follow these steps for correct grease volume:

- Clean the bearing cavity before adding grease
- Fill 15-20% of the cavity (1.2-1.8g for 6205 bearings)
- Run the bearing at low speed for 1 minute to distribute grease evenly

Over-lubricating adds 30% more grease, increasing operating temperature by 15°C and shortening bearing life by 40%. Under-lubrication reduces lubricant film thickness, leading to pitting after 2000 hours of operation.## Contaminant Entry in Lubrication System

Dirt, water, and metal particles in lubricant reduce bearing life by up to 70%. Use sealed bearings (like 6205-2RS) for applications with high dust exposure, such as construction equipment. For open bearings, implement a periodic lubrication flush every 500 hours to remove contaminants. Check lubricant color monthly: dark, gritty grease indicates contamination that needs immediate replacement.

For project-specific requirements, consult your bearing supplier. Contact MS Bearings for free technical support.

How often should I relubricate a 6200-series bearing?

For industrial applications operating at 1000 RPM, relubricate every 1000 hours. For high-temperature (120°C) environments, shorten intervals to 500 hours.
