Single Row Radial Ball Bearings
Single Row Radial Ball Bearings
Deep groove ball bearings are very widely used. A deep groove is formed on each inner and outer ring of the bearing enabling them to sustain radial and axial loads in either direction as well as the combined loads which result from the combination of these forces. Deep groove ball bearings are suitable for high speed applications. In addition to the open type, deep groove ball bearings come in a number of varieties, including pre-lubricated bearings, bearings with one or both sides sealed or shielded, bearings with snap rings and high capacity specification, etc.
Single Row Radial Ball Bearings - 8000, 87000, 88000, WC8000, WC8800 Series
Single Row Radial Ball Bearings - 8000, 87000, 88000, WC8000, WC8800 Series
8000, 87000, 88000, WC8000, WC8800 series deep groove ball bearings have different sizes from standard bearings, mainly manifested in the width position of the inner ring and the design of the sealing plate, which can meet the actual needs of different products
Expansion Compensating Bearings
Expansion Compensating Bearings
Expansion compensating bearings have the same boundary dimensions as standard bearings, except that a high polymer material with a large coefficient of thermal expansion has been inserted along the outer circumference of the outer ring. Due to the extremely small difference of thermal expansion attained between the fitted surfaces of the high polymer and the light alloy bearing housing, a good interference fit can be achieved with stable performance across a wide temperature range. Another advantage is a large reduction in the occurrence of outer ring creeping.
AC Bearings
AC Bearings
AC bearings have the same boundary dimensions as standard bearings with the addition of two O-rings imbedded in the outside circumference of the outer ring. This bearing has a steel housing, can withstand rotating outer ring loads, and is suitable for applications where a “tight fit” is not possible but the fear of creeping exists. With its capacity for axial load displacement, an AC bearing can also be installed as a floating side bearing to accommodate shaft fluctuations.

What Are NTN Deep Groove Ball Bearings?

NTN deep groove ball bearings are super versatile, designed to handle both radial and axial loads. They're perfect for different machines, from high-speed ones to those that need to carry heavy stuff.

 

NTN's Top-Quality Manufacturing

NTN, known worldwide for their bearing expertise, makes these deep groove ball bearings with the best quality and performance in mind.

  • They use high-quality steel and the latest heat treatment methods to make sure these bearings last a long time and keep working like new.
  • NTN also uses special seals to protect the bearings from dirt and keep the oil in, which really helps them last longer and stay reliable.

 

Key Features of NTN deep groove ball bearings

  • Handles Heavy Loads: Made to deal with both radial and axial loads effectively.
  • Super Precise: Built super accurately to work better, quietly, and with less shaking.
  • Extra Tough: Made with top-notch materials and strong seals to last through tough situations.
  • Easy to Look After: They're made to last long without needing much maintenance.

 

Types of NTN Deep Groove Ball Bearings

  • Single Row Radial Ball Bearings: These are standard bearings for handling both radial and axial loads, versatile for a variety of applications.
  • Single Row Radial Ball Bearings - 8000, 87000, 88000, WC8000, WC8800 Series: A specialized series with different seal and shield configurations, tailored for specific performance requirements.
  • Expansion Compensating Bearings: Designed to prevent creep by using a polymer material in the outer ring that adjusts to temperature changes, maintaining a stable fit.
  • AC Bearings: These have O-rings on the outer diameter to prevent creep, ideal for situations where the outer ring can't be tightly fitted and may face non-rotational loads. They also allow for axial movement to accommodate thermal expansion.
