Product Description

The 30x42x7 high precision bearing is engineered for demanding industrial applications requiring exceptional radial load capacity and rotational accuracy. This premium grade 30x42x7 metric seal integrates durable industrial shaft seals, offering IP68-rated protection against contaminants and lubricant leakage. Compatible with DIN-standard housings, it operates within -40°C to +150°C temperatures and withstands shaft speeds up to 8,000 RPM. The triple-lip design ensures low friction while maintaining sealing integrity under 25-bar pressure. Widely used in CNC machinery, automotive transmissions, and heavy-duty pumps, its chrome steel construction delivers extended service life despite harsh operating conditions. Installation requires specialized tools for optimal radial preload adjustment, with material compatibility verified for petroleum-based lubricants and moderate chemical exposure.
