uxcell 683 POM Plastic Bearings 3x7x3mm Glass Ball Nylon Cage 5pcs

• 683 (I.D.=3mm, O.D.=7mm, Thickness=3mm)
• The plastic bearings are light but strong with good self-lubricating performance and low friction
• POM races, Glass balls, Nylon cage for high rigidity and hardness
• Open on both sides for lubricating in place
• Specially for high precision and high speed operation

Description: -Single row, open-type, light weight plastic bearings. -This ball bearing has races made of POM (Polyoxymethylene) for high rigidity and hardness. The bearing balls are made of glass and the cage is reinforced nylon (GRPA66-25). -Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions. -With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance. -POM Bearings are better in strength and wear resistance, suit for operating from -60℃ to 100℃. -Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on. -With good self-lubricating performance and low friction, plastic bearings are specially for high precision and high speed operation.
