Working temperature and suffix meaning of C series single row deep groove ball bearings
C series single row deep groove ball bearings have different operating temperatures. The applicable operating temperature suffix temperature range of different sealing materials is not higher than +120 °C for open bearings. If +120 °C, please contact us. Z 30 °C to +120 °C if +120 °C, please contact us HRS 30 °C to +110 °C The temperature range is limited by the sealing material ELS 30 °C to +110 °CBRS 30 °C to +110 °C TVH 30 °C to +120 °C temperature The range is limited by the high temperature bearing suffix of the cage material S1 S2 S3 S4 Maximum operating temperature +200 °C +250 °C +300 °C +350 °C C series single row deep groove ball bearings without a cage suffix are all Riveted by stamping steel cage. Suffixes For the suffixes of existing designs, please see the table. Existing design suffix description design C internal structure improvement, C series standard design 2Z gap seal on both sides 2HRS contact seal on both sides 2BRS non-contact seal on both sides Z single side gap seal special design, HRS single side supply agreement Contact seal ELS One-sided contact seal 2ELS Two-sided contact seal BRS One-sided non-contact seal TVH Jaw type polyamide solid cage, steel ball guided inspection between polyamide and synthetic grease or lubricant containing EP additives Compatibility. At high temperatures, aging lubricating oil and its additives will reduce the working life of the nylon cage. The relubrication cycle must be strictly observed. For more information ■ For the technical principles of rolling bearing arrangements, please refer to catalogs HR 1 and GL 1. Design and safety guidance Equivalent dynamic load of bearing Equivalent dynamic load P is suitable for working conditions where the bearing is subjected to radial and axial loads at the same time. In fact, the rated life of the bearing is the same as under the combined load. For bearings bearing dynamic loads, the following formula can be used: load ratio and equivalent dynamic load Fa N bearing axial dynamic load Fr N bearing radial dynamic load e, X, Y coefficients, see table coefficient e, X and YP N combined Equivalent dynamic load of the bearing under load. To determine the coefficient e of P, X and Y are related to the ratio f0 · Fa/C0r and the internal radial clearance. The values u200bu200bin the table apply to the following common fits: ■ Shaft tolerance j5 or k5, bearing seat tolerance J6. Coefficients e, X and Yf0 coefficients, see page 8, table Fa N bearing axial dynamic load C0r N basic static load rating, see dimension table.
