Product description

Structure amp; introduction

Solid Collar needle roller bearing

The solid collar needle roller bearing has compact structure, small radial size and large load carrying capacity. It is suitable for the parts of which the radial overall size is limited. It is also wide applied to the situation where the shaft or housing has the swinging motion. In general, the needle roller bearing only withstands the radial load, not the axial load. When the shaft has axial load, it can be used in combination with other bearings. However, it does not limit the axial shift of shaft or housing. The limiting rotational speed of needle roller bearing is lower. In high rotational speed of main machine, the needle roller bearing with cage shall be chosen as far as possible. In compassion with other types of needle roller bearings, under the situation of same radial size, the needle roller bearing has the large load carrying capacity and high rigidity but has high friction torque.

This kind of bearing has many series with different structure and size. It is requested that the hardness, processing accuracy and surface roughness of shaft journal surface and rolling surface of outer housing be same as those of the collar of bearing. As for the needle roller with G2 class, the diameter varies within 2μm in group. Except the full complement needle roller bearings, they have the rigid cages, which can correctly guide the parallel axis line of needle roller.

Characteristics amp; classification

Model RNA, NK Needle Roller Bearings Without Inner Ring

The needle roller bearing without inner ring is suitable for the parts of which the radial size is limited. Because of no inner ring, the surface of shaft journal fitted with it is acted directly as rolling surface. It is requested that the surface hardness be no less than HRC60, surface roughness, no more than 0.63μm. This kind of bearing does not limit the axial shift of shaft and housing and has

Uroplatus ebenaui
Demons get such a bad rap these days. And... all other days, I suppose. But look at this cutie! Surely he wouldn't hurt a fly!

Image: Alextelford
Hmm? Oh. Turns out he would eat a fly. OK.

Image: Frank Vassen
But I bet he does it in the cutest way possible! The flies last thoughts would be something like, "This is actually kind of adorable. It's way better than getting eaten by a spider."

The Spear Point Leaf Tail Gecko is a member of the genus Uroplatus, the same as the Satanic Leaf Tailed Gecko (U. phantasticus). While it's great that one species got the moniker, to me they're all equally and wonderfully Satanic!

This species is found only in a tiny patch of northern Madagascar, as well as just off the coast on the even tinier and delightfully named island of Nosy Be.

They hang out in the trees, using their amazing camouflage to hide in plain sight during the day. At night, they wake up to hunt insects.

Image: Antonio Rodríguez Arduengo
The Spear Point gets their name from their tiny little tail which looks like something someone dug up from an ancient battlefield.

Image: Rob Meades
Despite that miniature tail, the Spear Point Leaf Tail Gecko is the biggest species in Uroplatus. It still only reaches about 7.5 cm (3 in) long, though. That's probably a good thing...

Clinging Jellyfish

RSQJ Seamless Lining Full Immersion Industrial Protective Protec

Gonionemus vertens
Jellyfish are known to be inveterate drifters. They love nothing more than to hang out in the water column, the careful fluttering and pulsing of their bell all but powerless in the face of a mild current.

But what if a jellyfish doesn't want to do that? What if they find a nice plot of ocean, verdant with plant life, the water a particularly delightful shade of blue, and they just want to settle down for a while? One tiny Hydrozoan has the answer.

Antennarius striatus
Pac-Man was always such a harmless soul, lost in the labyrinth of his own mind, chased by ghostly memories of his past and finding succour in a trail of psychoactive dots and the occasional fruit. He always seemed so happy. Or at least preoccupied.

He was never the same after the werewolf attack. He's so grumpy now. And he's completely abandoned vegetarianism...

Aspidistra

Aspidistras are famous for their ability to withstand and even flourish under the kind of neglect that would usually end in the crinkly, brown-leafed death of most plants.

But that's no excuse for neglecting their absolutely amazing flowers!

Nightmare Catcher

A Nightmare Catcher flitters through the rainforests of Bolivia, sticky net in hand.

Some say she feeds on nightmares, her gut so full of concentrated horror that the mere sight of her causes night terrors.

Others say that's silly, and she probably eats moths.

Still others say, "Yeah, that's what I meant. I actually have a terrible phobia of moths."

The IUCN's List of Threatened Species lists the Nightmare Catcher as 'Be Concerned. Be Very Concerned.'
