GGB Solid Polymer High Precision Plain Bearings BB 0810 EP

The Solid Polymer High Precision Plain Bearings, specifically part number BB 0810 EP, are designed for a variety of applications including medical equipment, scientific instruments, and office machinery. These bearings exhibit good performance in both dry and lubricated conditions, making them versatile for different operational environments. They are corrosion-resistant, suitable for humid and saline conditions, and offer a favorable price-to-performance ratio. The bearings can withstand a maximum dynamic load of 12,000 psi (80 N/mm¬=) and a static load of 6,000 psi (40 N/mm¬=). They operate effectively at temperatures ranging from -40°C to 140°C (-40°F to 280°F) and can achieve sliding speeds up to 700 feet per minute (1.0 m/s). The coefficient of friction ranges from 0.15 to 0.30, which is beneficial for applications requiring low friction. These bearings are compliant with RoHS, ELV, and WEEE specifications, ensuring they meet environmental standards. They are available in standard dimensions and can be customized for specific requirements, including thrust washers and sliding plates. The recommended shaft surface roughness is between 8 to 32 microinches (0.2 to 0.8 micrometers), and the surface hardness should be considered for optimal performance.
