Different load environment requirement for pu castor
Different load environment requirement for pu castor, environmental impact, as the market more industrial casters into the big market, at the same time of providing demand is also the main show of self value realization, increasing industrial castor also sample we go wrong, especially when the choose and buy performance is particularly prominent. With our whole body, select it from birth that moment start facing continuously, the choice of the industrial castor how do we choose? Is there any choose skills? Bearing is also called the rolling bearing, including: roller bearing, needle roller bearing and ball bearing. The main difference is the roller bearing used in the occasion of the radial pressure; Needle roller bearing is suitable for the radial pressure and rotation speed of the smaller occasions; Ball bearing is suitable for the occasion of small radial pressure and high speed. Almost the same in the same size, speed, the radial load cylinder is greater than the ball bearing axial load; Columns under axial load in the opposite direction or generally don't bear axial load, ( Individual models can be subject to bi-directional load) The free end, generally used in shaft; Ball bearings can withstand two-way load in the fixed end. Can tell, the same brand, same lubrication, under the condition of same load cylinder bearing is greater than the life of a ball bearing. Type polyurethane material with similar common thermoplastic plastic hardness and high mechanical strength, plastic processing methods may be used for production, at the same time, it has general elastomer elongation, elastic resilience and stress deformation recovery performance, use TPUR high strength and elongation at break, especially excellent tear resistance, bending resistance and wear, preparation, shoemaking, auto electrical, style can be used in many fields such as all kinds of wear-resistant, suspension parts. General good weatherability of TPU. Although it under long-term exposure to the sun's ultraviolet rays can produce slight yellow, but the performance of the materials will not be affected by too much. Usually used in outdoor TPU products are formulated with uv absorber, sometimes can add carbon black pigment when conditions permit, make material can effectively absorb ultraviolet light and ultraviolet shielding, improve the service life of materials. Disadvantages of this kind of product is oil resistant, heat resistant material and mechanical properties as the CPU.
