and rigidity Many of our precision bearings are also designed to meet the high-speed low-heat demands of the machine enabling non-synchronous run-outs below 00040 inch (1 um) This capability also known as non-repetitive run-out increases the accuracy repeatability and resolution of the machine The following special bearings are

Sizes range from tiny to extra large from the world's smallest track rail featuring a 1-mm width to those built for high rigidity and load capacity in huge machines Used in many industries such as semiconductor medical life sciences solar machine tool and construction Available styles include roller type rolling guides ball type rolling guides ball splines anti-creep crossed

Generally speaking precision ball bearings comply to ABEC-1 and ABEC-3 tolerances while high-precision ball bearings comply to ABEC-5 ABEC-7 or ABEC-9 tolerances Some general purpose ball bearings intentionally do not comply to the ABEC precision tolerance specifications and are not graded nor rated as such

Precision Bearings

This high precision bearing is commonly found on most machine tools where accuracy speed and rigidity are critical While precision angular contacts are available for purchase as a single bearing the majority of the time these bearings are sold in matched pairs to assure matching of bores

Canon's air bearings developed originally as a key component in super-high precision manufacturing technology have a special structure that gives them superior characteristics such as high rigidity high precision and high endurance The rotation precision of an air bearing is designed to be 0 05m maximum much more precise than ball

Applications In applications requiring a high degree of system rigidity cylindrical roller bearings are typically an excellent choice The QIBR assortment of super- recision p single row cylindrical roller bearings in the N 10 series is very well suited to meet this requirement as well as other demands placed on precision bearing arrangements

The compact construction the heat-treated steel parts and the ground gears on the involute guarantee transmission of high power ratings with amazingly low noise levels The spindle is supported by a set of preloaded precision ball bearings with oblique contact that ensure greater strength and rotation precision less than 0 01 mm

super precision angular contact ball bearings Figure 1 single row as single bearings or in sets contact angle 15 25 with large or small balls rolling elements made from rolling bearing ╳ Ready-to-fit machine element often defined in standards for transmitting movements loads and tilting moments with a high level of efficiency rolling bearings consist of rolling elements cages

QIBR Super Precision Cylindrical Roller Bearings are designed specifically to handle large radial loads in high-speed spindle applications that demand high running accuracy (runout) of bearing-spindle arrangements Features This lineup of bearing includes a basic series that meets ISO standards and a specified series targeting machine tools

MTS: For high-speed rotation Contains urea thickener and exhibits excellent heat resistance MTE: For high-speed rotation offers outstanding load capability ENS: Environmentally friendly due to its biodegradability QIBR's basic series of precision angular contact ball bearings

Because they can maintain their high-efficiency and high-functionality characteristics for an extended period of time they meet a wide range of needs from general industrial to precision machinery Caged ball guides provide high-speed operation in all mounting orientations The use of a ball cage eliminates friction between ball elements

Super Precision Angular Contact Ball Bearings

A Robust series of angular contact ball bearings for sustaining axial loads that achieves high-speed and high rigidity performance Features: The BTR series has a contact angle of 40 that features both high thrust rigidity and low heat generation properties

In precision high-speed applications a constant uniform preload is important To maintain the proper preload calibrated linear springs are typically used between the bearing outer ring and housing shoulder () With springs the kinematic behaviour of the bearing does not influence preload under normal operating conditions
