Bear Equipment manufactures sheaves out of a wide range of materials, including aluminum. Aluminum sheaves provide a lightweight and corrosion-resistant option for light-duty applications. The fabrication process starts with cutting aluminum roundbar into sheave blanks. The blanks are then placed in our CNC lathe to be precision machined to the desired profile and bore dimensions….
Bear Equipment can be YOUR crane wheel manufacturer. Crane wheels are used on overhead trolleys. Bronze is sometimes used due to its wear and corrosion resistance, along with spark resistance for explosion-proof applications. Bear’s crane wheels are precision machined in our CNC lathes to the exact taper and dimensions required for the application. Crane wheels…
Need a sheave for high load application, corrosive environment, where it is difficult to lubricate the bore option? A sheave with a POM bushing might be the solution.

One of the bore options for sheaves is bronze bushings. Generally, bronze bushings can be divided into 2 categories: oil-impregnated or grooved. Grooved bushings have a grooved machined in the inner diameter of the bushing to optimally distribute lubricant, which reduces friction and increases component life. Bear Equipment manufactures custom grooved bushings to meet the…
