Needle Roller NA Series Needle Roller
At Simply Bearings we stock a comprehensive range of NA needle roller bearings supplied by quality names like SKF, INA and IKO that are manufactured to be durable and hard wearing and are suitable for a range of applications where radial space is at a premium. Thanks to their high load carrying capacity and ability to operate at high speeds, these NA series needle rollers are suitable for use in the automotive industry where weight and performance are a strong consideration, in demanding environments like agricultural machinery and construction equipment where durability and reliability are paramount, and even in wind power generation that requires NA series needle roller bearings that can withstand challenging environmental conditions.
Available in both metric and imperial dimensions, our wide range of NA series needle rollers are fitted with an inner ring for ease of use mounting on unmachined shafts, where the inner ring acts as the raceway. Larger bearings are supplied with an annular lubrication ring. NA needle roller bearings represent an economic and cost effective solution owing to their ability to handle a given level of speed and load capacity, whilst maintaining the smallest cross section of any bearing type. Use of these bearings can lower costs by making machinery more lightweight and compact, since they have between 2 to 8 times the load bearing capacity per given mass compared to other types of bearings.
Simply Bearings can supply any of our 2 million plus products for free next day delivery in the UK when you order by 5pm. If you require international shipping, we offer extremely competitive rates - just select your chosen product and our smart shopping cart will calculate your worldwide shipping costs.
