About Bearings & Power Transmission
Bearings & Power Transmission brings together the rolling bearings, linear motion products, couplings, shaft locking devices and maintenance tools that keep rotating machinery running. Seven Star LLC, an independent supplier in Muscat, sources these items from SKF, Timken, NSK, HIWIN, Ringfeder, Dodge, Posi Lock, Graco, Fluke and UE Systems for industrial customers in Oman and the GCC.
What this category covers
Ball and roller bearings, mounted bearings and housings, HIWIN linear guideways and ball screws, couplings and shaft locking devices, and lubrication and bearing maintenance products such as greases, lubricators, pullers, induction heaters and condition monitoring tools.
Choosing the right product
Start from the load, speed, operating temperature and shaft arrangement. Bearing life depends on correct fit, clearance, lubrication and alignment as much as on the bearing itself, so mounting and maintenance products are listed alongside the bearings.
What to send for a quotation
Send the full designation printed on the part, the shaft and housing dimensions, and the machine type. We check each designation against the manufacturer documentation and propose the manufacturer’s successor when a type is obsolete.
What to include in your inquiry
These details let us quote the right item the first time.
- Manufacturer and model or part number
- Quantity
- Datasheet or nameplate photo
- Delivery location
- Required delivery date
Missing some of them? Send what you have. A nameplate photo or an old part number is enough to start.

Frequently Asked Questions
Which brands are listed in this category?
Bearings and mounted units from SKF, Timken, NSK and Dodge, linear motion products from HIWIN, shaft locking devices from Ringfeder, and maintenance products from Posi Lock, Graco, Fluke and UE Systems. Seven Star LLC is an independent supplier and does not claim any manufacturer appointment.
What does a bearing designation tell me?
A designation normally combines a prefix, a basic number that defines type and bore, and suffixes for seals, cage, clearance or precision. The basic number is decoded with the manufacturer catalogue, because prefixes and suffixes differ between brands.
Can bearings from different brands be interchanged?
Rolling bearings follow ISO dimension plans, so main dimensions of standard types usually match. Load ratings, internal clearance, cage and seal details can differ, so confirm against the manufacturer data before replacing.
Why do bearings fail early?
Common causes are contamination, insufficient or wrong lubrication, misalignment, incorrect fits and electrical current passing through the bearing. A failure analysis against the bearing damage chart in the maker documentation identifies the cause.
What should I send to get a quotation?
The complete designation from the part or the nameplate, quantity, shaft and housing size, application and any special requirement such as seals, clearance or temperature. A photo of the marking helps.
