Calidad e inspección
Aplicamos un estricto control de calidad a cada retén de aceite, desde la materia prima hasta el producto terminado. Los materiales entrantes se someten a pruebas de dureza, resistencia a la tracción, temperatura y resistencia al aceite. Durante la producción, se supervisan en tiempo real la temperatura de curado, las dimensiones del molde y la precisión del labio de sellado. Antes del envío, cada lote supera mediciones dimensionales, inspección visual, pruebas de fugas y pruebas de presión y envejecimiento. Gracias a equipos de prueba profesionales, procedimientos estandarizados, gestión de calidad ISO y trazabilidad completa de cada lote, cada retén de aceite tiene las dimensiones exactas, un sellado hermético y una estanqueidad fiable, lo que garantiza una calidad constante y confiable para nuestros clientes.

Preguntas frecuentes-
How do I choose between FKM and NBR oil seals?
It depends mainly on operating temperature, media and speed. FKM (fluorocarbon) works from −25 to 200°C and resists oils, acids, alkalis and many chemicals, ideal for high-temperature, corrosive conditions and synthetic oils. NBR (nitrile) generally works from −40 to 120°C, offers good mineral-oil and wear resistance at lower cost, and suits normal-temperature general use. Choose FKM for strong solvents, high-temperature oils or longer service life.

¿Cuáles son los requisitos del eje y del orificio de la carcasa para la instalación?
El eje debe ser liso, con una rugosidad superficial de Ra 0,2–0,8 μm y una dureza de al menos HRC 35 (HRC 45+ para alta velocidad). Añada un chaflán de entrada de 15°–30° al eje y al orificio, y elimine todas las rebabas para evitar dañar el labio. Un orificio de alojamiento típico es H8 y el eje f7/f8; recubra el labio y el eje con aceite lubricante limpio antes del montaje.
-
Which way should the lips face on a double-lip (TC) seal?
The primary lip (the side with the garter spring) must face the media being sealed—the oil cavity—to retain lubricant. The secondary lip (no spring) faces outward to block dust and contaminants. If sealing is needed on both sides, use a paired-seal arrangement or a dedicated double-acting design.
-
What are the common causes of early leakage?
Typical causes include wrong selection (material/temperature/speed mismatch), oversized shaft or bore, rough or scratched shaft surface, a cut lip or dislodged spring during fitting, reversed lip direction, dry running from insufficient lubrication, excessive shaft eccentricity or run-out, and contaminated grease. Follow the installation guide and check shaft alignment.
-
What is your MOQ?
Small MOQ for standard stock products. Custom molded items will be quoted separately; small batch sampling is supported.
-
What is your lead time?
