R188vs 608

Other than that, the characteristics of the R188-2Z/SS AKN are similar to those of standard chrome-steel deep groove ball bearings. Like all single-row deep groove ball bearings, they are of simple and sturdy design. They are practically maintenance-free. Deep groove ball bearings are especially suitable for accommodating radial loads. To a lesser extent, they can also be axially loaded in both directions. Their ability to operate under both light axial and moderate radial loads ensures versatility, making them suitable for a wide range of uses, from industrial machinery to precision instruments.

[Remarks] 1. This table is applicable to cast iron or steel housings. 2. If only central axial load is applied to the bearing, select such tolerance range class as to provide clearance in the radial direction for outer ring.

The R188-2Z/SS AKN is a stainless steel deep groove ball bearing. Stainless steel is highly corrosion-resistant. This makes stainless steel bearings suitable for environments where the presence of moisture or chemicals is a factor. These environments include the food industry, and pharmaceutical- and chemical applications. Moreover, stainless steel can withstand relatively high temperatures. However, stainless steel bearings do have slightly lower load carrying capacities compared to chrome-steel bearings.Other than that, the characteristics of the R188-2Z/SS AKN are similar to those of standard chrome-steel deep groove ball bearings.

They are frequently used in applications where hygiene and cleanliness are crucial, such as medical equipment and food processing machinery. These bearings also perform well in high-humidity or wet conditions, offering reliable, long-lasting performance with minimal upkeep.

As described in Section 9-3, the characteristics / magnitude of the bearing load, temperature, mounting / dismounting methods and other conditions must be considered to choose proper fits. Past experience is also valuable. Table 9-3 shows standard fits for the metric series bearings; Tables 9-4 to 9-8 tabulate the most typical and recommended fits for different bearings types. 『Table 9-4 (1) Recommended shaft fits for radial bearings (classes 0, 6X, 6)』 『Table 9-4 (2) Recommended housing fits for radial bearings (classes 0, 6X, 6)』 『Table 9-5 (1) Recommended shaft fits for precision extra-small/miniature ball bearings (d＜10mm)』 『Table 9-5 (2) Recommended housing fits for precision extra-small/miniature ball bearings (D≦30mm)』 『Table 9-6 (1) Recommended shaft fits for metric J series tapered roller bearings』 『Table 9-6 (2) Recommended housing fits for metric J series tapered roller bearings』 『Table 9-7 (1) Recommended shaft fits for inch series tapered roller bearings』 『Table 9-7 (2) Recommended housing fits for inch series tapered roller bearings』 『Table 9-8 (1) Recommended shaft fits for thrust bearings (classes 0, 6)』 『Table 9-8 (2) Recommended housing fits for thrust bearings (classes 0, 6)』

[Notes] 1) Symbols T and L means interference and clearance respectively. 2) In the columns "single plane mean outside diameter deviation" and "fit" upper row values are applied in the case of D≦18mm, lower row values in the case of 18 < ＜D≦30mm.

[Notes]1) Light, normal, and heavy loads refer to those with dynamic equivalent radial loads (Pr) of 5 % or lower, over 5 % up to 10 % inclusive, and over 10 % respectively in relation to the basic dynamic radial load rating (Cr) of the bearing concerned.

2) IT 5 and IT 7 mean that shaft roundness tolerance, cylindricity tolerance, and other errors in terms of shape should be within the tolerance range of IT 5 and IT 7, respectively. For numerical values for standard tolerance grades IT 5 and IT 7, refer to supplementary table at end of this catalog.
