应用场景

Used for support, friction reduction, dust-proofing and oil sealing of rotating/reciprocating parts, keeping the lubrication system clean and reducing wear, suitable for heavy-duty continuous operation

安装说明

1. Clean the journal and housing bore and apply clean grease before installation; 2. Press in with special tools; direct hammering is prohibited; 3. Confirm the seal lip direction faces the medium side

常见问题

What causes rapid wear of bushings?
Main causes include: poor lubrication or oil contamination, excessive journal surface roughness, improper fit clearance, overload or impact loads, and abrasive particles entering due to uncleaned installation. Regularly test oil cleanliness and clearances.
How to troubleshoot seal ring leakage?
First check whether the seal is aged or deformed (beyond shelf life or high-temperature service), then check the journal surface for scratches and wear, and finally check whether the installation direction is correct (lip facing the medium side). Check mating surfaces at the same time when replacing.
What is the replacement cycle for bushings and seals?
Under normal conditions, the replacement cycle is 12-24 months for bushings and 6-12 months for seals. Decide based on monitoring data: replace promptly when clearance exceeds 1.5 times the initial value or abnormal temperature rise or vibration occurs.
