The SKF SYR H is a pillow block assembly that includes an insert bearing, made for mounting on shafts and providing firm support in belt, chain or roller drives. It fits equipment where the bearing needs to be aligned and secured to a frame. Installation is straightforward and maintenance access is simple. MR Industrial Accessories supplies this SKF line with technical guidance to match the shaft diameter and operating conditions.
The SYR H code breaks down into three parts. SYR denotes the housing style for an insert bearing. The trailing H tells you the insert uses set screws on the inner ring to lock onto the shaft. Numbers placed in the middle, such as in SYR 1.1/2 H or SYR 2 H, give the shaft size in inches. So SYR 1.1/2 H fits a 1 1/2" shaft, SYR 1.3/4 H fits 1 3/4" and SYR 2 H fits 2". This naming lets you identify the needed size at a glance.
These housings appear across many industries in the United States and Latin America. You will find them on belt conveyors, bucket elevators, mills, mixers, fans and agricultural machinery. They also serve food, chemical and process operations that need rugged, easy-to-clean support. The pillow block shape simplifies mounting on profiles or beds, and the insert bearing absorbs small angular misalignments. MR Industrial Accessories offers them for both replacement and new projects.
When choosing a housing, consider the shaft diameter, the radial and axial loads you expect, and the surrounding environment. Set screw locking suits shafts with h6 tolerance or similar and controlled tightening torques. Verify alignment between housings and keep axial loads within limits. Factory lubrication can be supplemented based on the duty cycle. The insert seal guards against dust and moisture; for harsh conditions, look at versions with extra seals. Proper installation helps the assembly last longer.
For equivalents, SKF SYR H housings can be swapped with other brands that use the same inch-based shaft nomenclature and locking method. Still, always check base dimensions, center height and insert type, because these can differ between manufacturers. The SYR H series is a widely used reference, but tolerances are not identical across all brands. When replacing an existing housing, compare the critical dimensions first.
To request a quote for the SYR H housing you need, send the full part number by WhatsApp, for example SYR 1.7/16 H or SYR 2.3/16 H. If you do not have it handy, tell us the shaft diameter and working conditions. At MR Industrial Accessories we help you pick the right option and complete the purchase.

Frequently asked questions
- What does the H mean in the SYR H part number?
- The H shows that the insert bearing locks onto the shaft with set screws on the inner ring. This works with h6-tolerance shafts and allows position adjustment. It is common where little axial torque is transmitted.
- How do I choose the right diameter for my shaft?
- The number in the part number, like 1.1/2 or 2, is the shaft diameter in inches. Measure your shaft with a caliper and pick the matching housing. If the shaft is worn, consider repair or an insert with more tolerance.
- Is this housing suitable for axial loads?
- The SYR H housing is mainly for radial loads. Axial loads should be limited and assessed for your application. For significant axial loads, contact our technical team to select a suitable solution.
