Below are moving bearing option requirements to take into consideration for applications:


  • Available room: A bearing’s diameter, among the key dimensions, is generally established by the maker’s design as well as its shaft size. Small-diameter shafts can be fitted with any type of round bearing, such as FTW Bearings [ตลับลูกปืน FTW, which is the term in Thai]. In addition to deep groove sphere bearings, needle roller bearings can additionally be utilized. Bearings for large-diameter shafts consist of round, taper, circular, and deep groove sphere bearings. In scenarios where radial space is limited, tiny cross-section bearings are more effective.
  • Tons: A bearing’s dimension is typically identified by the magnitude of the tons. Generally, roller bearings sustain heavier tons than similar-sized round bearings, and bearings with a full complement of rolling aspects can suit larger loads than captive bearings. In general, sphere bearings sustain light to moderate tons. Bearings with rollers are usually the better-suited selection when bearings need to sustain heavy tons or when shaft diameters are huge.
  • Imbalance: Misalignments are brought on by shafts flexing under tons, when bearing seating is not machined to the same elevation, or when bearings are spaced far apart. Deep groove round bearings along with round roller bearings cannot accommodate any misalignment or can fit small imbalances unless forcibly. Bearings that self-align such as spherical roller bearings, as well as round roller drive bearings, can suit imbalance and make up for the first misalignment caused by machining and mounting errors.
  • Precision: Setups that need high running precision, as well as applications that need broadband need bearings with higher accuracy. This is typically the case in medical and aerospace applications. High precision bearings are usually made according to deep groove sphere bearing or angular contact with bearing standards, yet have smaller-sized resistances than typical bearings.

Speed: A rolling bearing’s rate is restricted by the allowable operating temperature level. For the high-speed procedure, bearings with low rubbing, as well as subsequently reduced heat generation inside them is most appropriate. Thrust bearings, by their style, cannot accommodate as quick a rate as radial bearings.
