The ST series take-up bearing unit with insert bearing is a mounted assembly used to maintain tension in chain or belt drives. The unit combines an insert bearing with a take-up housing that allows position adjustment and compensates for stretch or slack in the system. It is used in conveyors, elevators and machines where the take-up prevents jumping, premature wear and loss of efficiency. MR Accesorios Industriales carries this SEALMASTER line in Buenos Aires, Argentina.

The ST series designation is read as a numeric code preceded by fixed letters: for example, ST-8, ST-9, ST-10, ST-11, ST-12, ST-13, ST-14 and ST-15. The final number identifies the assembly size and is related to the dimensions of the insert bearing and the housing. In this family, the letters ST refer to take-up housing and the number allows ordering the series from smallest to largest capacity. To select the correct part number, you must cross-reference the shaft diameter, the locking type and the application conditions.

These take-up housings appear in food, cement, mining, grain and aggregate processing plants. In Argentina they are found in belt and chain conveyors, bucket elevators, conveyor belts in storage plants and packaging lines. The main function is to absorb the length variations that chains and belts undergo with use, maintaining adequate tension so that the drive does not slip or overload. They are also used in agricultural machinery and material handling equipment.

To choose the take-up housing, it is advisable to check the shaft diameter, the insert bearing type (set screw, eccentric or adapter) and the sealing system, which defines resistance to dust, water and washdowns. Installation requires aligning the take-up with the drive and fastening it to a rigid base; poor alignment accelerates wear of the insert and the chain. Lubrication of the insert bearing must follow the manufacturer's recommendation and be renewed according to the working environment. In applications with heavy contamination, higher-protection seals are recommended.

ST series take-up housings can be interchanged with equivalent units from other brands that share the same shaft diameter and mounting pattern. The key is to compare the critical dimensions: shaft diameter, bolt hole spacing, center height and insert type. It is not enough for the numeric code to match; the housing geometry and adjustment system must be verified. MR Accesorios Industriales will indicate the compatible alternative if the original part number is not available.

If you need a take-up housing for your drive, send the part number ST-8, ST-9 or the corresponding one via WhatsApp to MR Accesorios Industriales. You can also send a photo or the shaft and housing dimensions, and we will quote the unit or the alternative that best suits you. With more than 80 years in the field, at MR we know the applications of these assemblies in Argentine industry and we help you resolve the tension of your equipment.
