Founded in August of 2000, WD bearings is a technology-oriented group, specialized in R&D, manufacturing, sales and service of high quality bearings. Here, WD bearings is honored to recommend some new bearings for you! ◆WD Bearings Supplier◆--Rolling Mill Bearings WD four-row cylindrical roller bearingsare used almost exclusively for the roll necks of rolling mill stands, calenders and then roller presses. Their friction is low compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are especially suitable for rolling mill applications where the rolling speed is high. The low bearing cross section allows for relatively large roll neck diameters in comparison to the roll diameter. Since pretty many rollers can be incorporated, the radial load carrying capacity is exceptionally high. WD four-row cylindrical roller bearings are only able to accommodate radial loads. They are therefore mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings, either radial or thrust designs, which take up the axial loads. ◆WD Bearings Supplier◆--Tapered Roller Bearings WD tapered roller bearings have tapered inner coupled with outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes tapered roller bearings especially suitable for the accommodation of combined (radial and then axial) loads. The axial load carrying capacity of the bearings is largely decided by the contact angle ; the larger contact angle the greater axial load carrying capacity . An indication of the angle size is given by the calculation factor ; the larger the value of , the larger the contact angle together with the greater suitability of the bearing for carrying axial loads. Tapered roller bearings are normally separable, i.e. the cone, consisting of the inner ring with roller together with cage assembly, can be mounted separately from the cup (outer ring). WD tapered roller bearings have the logarithmic contact profile that provides optimum stress distribution over the roller/raceway contacts. The special design of the sliding surfaces of the guide flange large roller ends considerably promote lubricant film formation in the roller end/flange contacts. The resulting benefits include increased operational reliability together with reduced sensitivity to misalignment. ◆WD Bearings Supplier◆--Cylindrical Roller Bearings Double Row Cylindrical Roller Bearing WD cylindrical roller bearings have many designs, dimension series not to mention sizes. The majority is single row bearings with a cage. Single double row full complement bearings (without cage) complete the WD standard assortment for general engineering. Bearings with a cage can accommodate heavy radial loads and also operate at high speeds. Full complement cylindrical roller bearings are suitable for exceptionally heavy radial loads at moderate speeds. The rollers of WD cylindrical roller bearings are key components. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and then optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability a greater insensitivity to misalignment.
