Frequently Asked Questions (FAQ)
Yes, all technical resources on this page are completely free. The V-belt pitch length calculator, ISO bearing tolerance chart, thread identification guide, motor efficiency comparison, and gasket compatibility matrix require no login or registration. They are maintained by the STARNEX engineering team for plant maintenance professionals across Kenya and East Africa.
The V-belt pitch length calculator uses the standard ISO 4184 / DIN 2215 formula (Lp = 2C + 1.57(D+d) + (D-d)²/4C) and returns results matching published belt manufacturer catalogs. The motor efficiency tables reflect IEC 60034-30-1 minimum efficiency requirements for IE1 through IE4 classes. KPLC electricity cost models use current published industrial tariff rates. Always verify critical sizing against the belt or motor manufacturer datasheet before ordering.
Yes. The ISO 286 shaft and housing fit tolerances (k5, m5, h6, H7, J7) are international dimensional standards applied universally regardless of bearing manufacturer. Whether you are installing an SKF 6205, an NSK 22220, or a Timken 30208, the shaft and housing machining tolerances are identical for the same bore diameter and application type.
Absolutely. WhatsApp a clear photo of the thread to +254 740 459 672 and our technical desk will identify whether it is BSPP (parallel), BSPT (tapered), NPT, JIC, or metric. We stock BSP and NPT hydraulic fittings, adaptors, and thread gauge sets at our Enterprise Road trade counter in Nairobi for same-day collection.
Yes. STARNEX Industrial Spares Ltd stocks genuine V-belts (Continental, Gates, PIX), ball and roller bearings (SKF, NSK, Timken), hydraulic fittings (BSP, NPT, JIC), three-phase electric motors (ABB, Siemens, WEG in IE2 and IE3), and gasket materials (EPDM sheets, Viton O-ring cord, Klingersil C-4400, ceramic rope) at our trade counter on Enterprise Road, Nairobi Industrial Area. Same-day Nairobi dispatch and next-day upcountry delivery are available.
