Description
SKF SY 45 TF/W64F is a y-bearing unit reference, within Bearing housings. Request a quote for SY 45 TF/W64F via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SY support with SKF insert bearing is an assembled unit that combines a split bearing housing with a ball insert bearing, ready to mount on shafts and structures. It is used to guide and support rotating shafts in transmission equipment, providing a compact solution that is easy to align. MR Accesorios Industriales supplies this line, backed by more than 80 years of technical experience in the field.
The SY designation identifies the category of split plummer block housings with insert bearing. The numbers that follow indicate the shaft diameter for which they are dimensioned, and the suffixes TF and W…F provide sealing and design variants: TF usually indicates a standard seal, while W…F refers to a version with additional features, such as greater protection or suitability for specific environments. For example, SY 45 TF/W64F corresponds to a unit for a 45 mm shaft with TF sealing and W64F variant. Always check the full part number on the product label or on the equipment drawing.
These units are used in a wide variety of industries in Argentina: from conveying lines and bottling plants to mills, mixers, fans and agricultural equipment. Their split design facilitates assembly and disassembly without the need to dismantle the shaft, which is ideal for in-plant maintenance. They are also common in applications where the shaft must rest on metal structures or masonry, with the possibility of adjusting alignment through the slotted holes of the housing.
To select the right unit, take into account the shaft diameter, the expected radial and axial loads, and the environmental conditions. Sealing is key: in environments with dust, moisture or frequent washdowns, a design with additional protection is advisable. During assembly, ensure a flat and rigid surface, tighten the bolts evenly and check the alignment of the shaft with the insert bearing. Lifetime lubrication is common in these inserts, but in severe applications periodic relubrication may be required.
As for equivalents, SKF SY units can be interchanged with units from other manufacturers that follow standardized dimensions, such as the SY series of different brands. However, not all suffixes match: a TF may have an equivalent under another designation. Therefore, when looking for a replacement, it is essential to compare not only the shaft diameter but also the type of sealing, the fixing system and the tolerances. MR Accesorios Industriales can advise you to find the right alternative without inventing part numbers.

Frequently Asked Questions
- What does the TF suffix mean on an SY support?
- The TF suffix indicates a design with a standard seal, which protects the insert bearing against moderate dust and moisture. It is important to check the full part number, since it can be combined with other variants such as W64F for specific applications.
- How do I choose the correct diameter for my shaft?
- The number that follows SY in the part number indicates the shaft diameter in millimeters. For example, SY 45 corresponds to a 45 mm shaft. Measure the shaft with a caliper and consult the dimension table to ensure a correct fit.
- Does this support require periodic lubrication?
- Many insert bearings come lubricated for life, but under severe conditions relubrication may be necessary. Review the manufacturer's recommendations and the working conditions to define the appropriate frequency.
