When customers lack bearing drawings, accurate reverse engineering depends on three core measurements: overall dimensions, mounting hole chord lengths, and gear parameters. Precise on-site measurement by professional engineers ensures correct
We solve the transportation challenges of ultra-large slewing bearings through customized packaging, container optimization, heavy-lift vessels, controlled road transport, and destination-oriented design. From standard containers to heavy-lift ships, our solutions
Quantitative evaluation of slewing bearing wear should focus on four core rotational accuracy indicators: bearing clearance, axial runout, radial runout, and gear runout. Among them, bearing clearance is the most
This article provides a practical, engineering-focused guide to the installation, bolt tightening, lubrication, and maintenance of slewing rings used in port portal cranes. It explains how mounting base preparation, pre-installation
Based on proportional calculations, the steel balls in slewing bearings are generally taken as height H × 0.375 or 0.45. If the bearing ring height is 70mm, then 70 ×
How to calculate crane bearing pressure: Use the formula 𝑝 =𝐹/𝐴, where 𝑝 is pressure, 𝐹 is the total applied load (radial, axial, and dynamic), and 𝐴 is the effective
Food-grade bearings must meet strict standards to ensure safety in food equipment. They are typically made from stainless steel or ceramics, produced in clean environments, and lubricated with NSF H1-approved
Bearing letters and numbers are industry codes that define the product’s features.
RS/RZ: Plastic seals for moisture, dust, and corrosion protection.
ZZ/2Z: Steel shields for dust protection with low friction.
